Americans often think the shitty experience they have in their country applies universally. Ex: The bus & light rail is bad and slow, so therefore it will always be bad everywhere. Americans haven't lived or even travelled to places in europe and asia with functional transit systems and do not realize what they are missing.

Another common american assumption is: apartments are only for the poor, so they will always be made shitty with bad soundproofing when you can make them with good soundproofing as a standard and a good amount of square feet. Or metros are always dirty, dangerous and the gross homeless live there, while that is also a pure policy choice of america.

I grew up in north america, lived in places with good metros and good apartments, and then moved to America. America doesn't know how bad they have it.

We should be aiming for some degree of density. I would hazard a guess that size is largely dependent upon what a person wants out of life.

Infrastructure is very expensive to build and maintain, and everyone demands it in multiple forms (roads, water, sewage, and power at a minimum). Containing the costs by reducing either extent or capacity would allow us to allocate those resources to other things, things that could improve the collective quality of life.

As for decentralization, it depends upon how it is done. I've lived in or visited towns with a few thousand people. Nearly everything one needed was within walking distance, though people often left town for things they wanted. I've also lived in similarly sized urban communities where virtually nothing one needed was within a reasonable walking distance. Suburban communities often take the latter to the extreme. What was the difference? Everything in the small town was centralized, yet businesses and services in those urban communities were effectively decentralized.

Let's say you build a bunch of small towns to decentralize the population and get away from feeding money back into the hands of those who own and control cities. You now have another major consideration: are people going to live most of their daily lives in those towns, or are they going to live in one town and work in another? A big part of the reason why people spend so much of their life commuting, whether it is by car or train, is because opportunities (may it be home ownership or careers) don't necessarily fall in the same place.

Yes, you can get an affordability crisis anywhere you make it illegal to build housing. Nobody is arguing that. The point is that you also get an affordability crisis simply by pushing the transportation infrastructure to the point of failure, and then reject density.

>Is "make today's cities larger and denser forever" really the solution? Or can we figure out ways to disperse and decentralize things instead of just feeding more money back into the hands of those who own and control the current cities?

This is literally what's happening in every tech satellite city, the point is that many-if-not-most of our urban centers are already at their transportation capacities, simply because that is the suburban development model: it's extremely cheap until suddenly it's no longer functional. The suburban model has no equilibrium, it's a cascade, once the planned automobile infrastructure reaches capacity, you cannot increase it at a rate that is sustainable. Thus, once that capacity is gone, suddenly the real estate in the core becomes extremely valuable -> which incentivizes density -> which further strains peak infrastructure -> which increases the value of core real estate -> which further incentivizes density -> etc. -> etc. -> etc.

We can't wish this away, beyond wishing other people just didn't exist. It's like wishing that other people would take the bus, but not wanting to take it yourself. Nobody in the bay area wants to move to affordable Red Bluff, CA, without a reason, much less the CEO of a major corporation moving their entire company there out of the kindness of his heart we he or she already has a house and friends in Atherton.

Not to say, in a vacuum, multi-family housing won't provide more housing units per unit of land area than single-family. Clearly, it will. But unless you build every city from scratch to house 20 million people, whether you started with single-family or multi-family, the most desirable cities will end up in a future state whereby more people want to live there than housing exists for, and even if regulations and zoning allow you to build higher and denser than is currently done, to do it where people want to live, you'll have to tear down existing buildings, including existing housing, and many of the owners and occupants of that housing won't want that. You'll also need to run more utility lines, build new pipes, run them under existing roads, which means shutting down those roads, and even if they're perfect utopian European roads that have zero cars on them and only have pedestrians and bicycles, the user of those roads are still going to get annoyed and inconvenienced, and it's going to cost more to do this than building new housing where nobody currently lives, pretty much no matter what.

Why are you acting like driving a vehicle and being a passenger in a vehicle are the same experience? One is clearly more demanding and inhibiting than the other.

On a train you can work, read, listen to a podcast, sometimes eat... Lots of things you can't do while in a car. Unless your job is driving. Which, if you commute for work, it kinda is.

The pandemic showed that millions of us can work from home. My office was closed for about 2 years. Our stock price shot way up.

There were lots of stories about the environmental benefits. Air pollution in big cities decreased dramatically. Wildlife started returning in places.

We keep building commercial real estate and most people I know have little desire to commute to the office and sit in a cubicle disturbed by other people constantly.

I would severely limit commercial real estate building permits, encourage companies to have employees work at home via tax breaks or whatever. This will help with the housing issues, greenhouse gas emissions, decrease the need for new roads because of less traffic.

Everyone wins except dumb control freak managers and restaurants that do lunch in the business areas.

Unless forced to due to scarcity, dense development does not really clump up together all at once for good reason, since clumping up will drive up costs in a hyper local area. Tokyo for example, has a lot of detached housing, even in the central wards. The density there is more pockmarked and random, and notably never really concentrates all that highly; there is not a single Japanese building in the top 100 skyscrapers, because skyscraper concentration is an artifact of how we force dense developments only in certain places.

If it’s not any of these it’s owned and thus controlled by someone.

Tokyo Metro handles 6m+ riders a day with a population of 40m. So, yes, at least until you surpass 40m people.

> Or can we figure out ways to disperse and decentralize things instead of just feeding more money back into the hands of those who own and control the current cities?

“Disperse and decentralize” is exactly how every city I have ever been to is built.

Everyone complains about the city’s endless verticalização (verticalizication) because they like the idea of old houses, but I say keep it coming.
