Even in cities that don’t require that, rents are still expensive (with the exception of Tokyo where you can rent a 2.5 tatami sized apartment, shared toilet, no central heating, for $300/month).

Maybe you've got some good examples from other countries, but here in the US the only major city with reasonable zoning is Houston which has quite affordable homes.
I wouldn’t mind living in Tokyo, Houston doesn’t tempt me at all. I assume much of its affordability is related to demand, and the fact that given a lack of zoning it can sprawl forever (also reducing its appeal). I met a homeless person in Seattle from Houston, even the homeless don’t find the city desirable (though it might be due to weather?).
“In the city of New York there were laws
passed to push the private sector out of the SRO business [and eliminate SROs] on the theory that SROs were inhumane. Consequently, people sleep on grates outside.” — George McDonald
SROs, residential hotels, boarding houses and the like were all banned in the 1950s (and the surviving ones dismantled through the 1980s), a loss of about 100,000 units of affordable housing.
