I guess it's true that money != happiness. There's always more you could have.
But every single American friend I have either has a home, or dreams of home ownership in the suburbs. And it makes sense, if I grew up in a home with a yard, I would probably want something similar for my children too. That kind of emotional connection is hard to overcome.
In the bay area for example it doesn't make ANY sense to buy right now (Price to rent ratio, google it) but still people are flocking on every shitty apartment on sale. That's because they want to feel that little ego boost when they say they are "homeowners".
All the sfba homeowners who bought for cheap but are now sitting on millions of dollars of property could easily make a tidy sum if they were willing to sell for less but they will feel like they left money on the table. Ultimately when the bubble pops, everyone will sell for less but they will all think it’s perfectly rational because the “market is down”. I don’t get that perspective at all. Buy low and sell high, within reason.
I want a home that I can modify to my desires and use as I please. I want a woodshop at my home or to do some small machining in my garage - can easily do it if I own the home. As it stands, my landlord gets on my case about even the smallest of changes or for even using my god damn backyard patio. (He says my furniture ruins the "cutesy aesthetic" of the exterior; the oh so visible area that no one but us can see)
It's pretty annoying and home ownership doesn't remove all the burdens/restrictions but it is better than the overbearing landlords that seem overly abundant in the bay area.
