Yeah, the USA (in general) won’t do anything at all.

A few medium-sized cities like Austin are the exception to this.

???

Lots of large cities are building a bunch. Every large city in Texas, Phoenix, Tucson, Salt Lake, etc.

Florida feels like every square mile is under construction with new builds too.

Those could be called medium sized.

Those areas are far larger than San Francisco

The whole bay area not the city proper
