Zoning itself is quite a loud say from the government about what someone may do in their personal private time in their personal private property. For example, you can't run a bakery in your personal private time in an area zoned only for residential use.
Do you think zoning should not be legal?
The city of Houston has no zoning laws - you are free to build wherever, whatever, occupied by whomever, subject only to market forces and contracts. The result has been a sprawling, car-driven metropolis where to get anywhere, you need at least a 20-minute drive in a car. My sister lives in a development of over 10,000 people, all single-family homes spread over several square miles of drained floodplain. There is basically zero commercial or office space in the development; to get to the nearest restaurant or supermarket, she needs to get on the highway. Her husband has roughly an hour commute to work; she had a 45-minute commute when she was working. The highways are so congested at rush hour that you use privately-developed toll roads to get across town if you have the money.
There's also various absurdities like people being sold homes inside flood-control reservoirs, or sex shops next to preschools, or residential homes next to chemical storage tanks.
On the plus side, housing is really cheap - the same house that would go for $1.5M in my neighborhood in Sunnyvale (a 3BR2BA on 1/4 acre) goes for under $200K in Houston. My sister lives in a gorgeous 5BR4BA waterfront property that cost < $600K; you literally can't find anything for that price where I live.
Most of what you write here seems to confirm my point, with the exception of the zero commercial in your sister's development. Should we assume there is some sort of contract or HOA enforcing that? If so, I guess that isn't zoning, but it acts in largely the same way, doesn't it? Also, look at any other metropolis in Houston's timezone, and you'll find identical suburban situations. So maybe we can't blame the lack of zoning here? As I'm sure you're aware, in many situations zoning has been blamed for unmixed development.
It's possible that Houston might do some sort of BRT someday, which would help a great deal with commute times. BRT could even use some of those horrible un-American private roads. Already, the commutes you describe are better than those in lots of cities with extensive public transit.
