It only makes sense to sprawl like in Houston if you never mind spending 3-4 hours commuting to work and back. Or if you can't afford anything better.

Ask well-paid people who keep renting apartments in Manhattan, or in downtown SF, to say nothing of Tokyo or Seoul.

I realize "makes no sense" carries a double meaning here. I am speaking of the system-level decisions which end up actually producing infrastructure. You're right that sprawl is absolutely inhumane – we should absolutely nudge processes/incentives such that it's discouraged, but doing so is not as simple as just "get rid of zoning."

Average commute time in Houston is just under half an hour (depend on which source you read, varies from 26-29 in my quick search). Sure you can do commutes more than an hour long, but people generally don't - if they get a new job more than about half an hour away they will move.

Much easier to do with self driving cars though. Remember the promise? “Take a nap in your car and arrive at your destination” or “be productive on your commute”.
