It also doesn't make sense to have everyone in the country try to live in a dozen cities.

Those cities themselves are unsustainable: SF, Portland, and Seattle are all literal shitholes, due to failed civic leadership and uneconomic policies.

As a civilization, we need to figure out how to reduce the pressure to collect in a handful of places, and spread ourselves back over multiple locations and jurisdictions -- because it's clear that's a better plan.

Our current system is optimized for a few major players, and it's collapsing. They're right to worry, and try to adjust it.

Figuring out how to get people to live in already affordable places is the only way to reduce the pressure on those cities and create housing affordable and livable for average people.
