Your solution to "the stupidity of the housing markets in cities" is to increase their demand, and to make housing overall more unaffordable? Sorry, no, I'm not going to raise my family of six plus a dog in a high rise. Encouraging happy, productive families by subsidizing suburbs is good.
> increase their demand, and to make housing overall more unaffordable? You're not thinking systematically. Increased demand isn't the only variable. Consider also how gov't and the market respond to increased demand and need, especially if the paradigm of normative human settlement changes. Social pressure forces changes. Diffusing pressure allows gov'ts to kick the can down the road, which is what led to the suburb…
The government already isn't effectively responding to increased demand and need, so I really disagree that making the problem worse will overall help anything. That is basically accelerationism.
The rest of your post I disagree with from value-based first principles, e.g. "children are shackled and isolated" and "you can't do...anything without driving", as though the only things for children to do in the world are shop and consume in an urban center, so there is no point discussing it.
