California basically did this[1]. Sadly though the desirable coastal areas are literally full and all spoken for and even without any real zoning anymore there’s nowhere to actually build. So you’re gonna need to eminent domain some Malibu mansions to make room for the non stop line of 1+5s from LA to SF.

It’s also interesting to me how many people propose increasing supply when there is nowhere to build, but can’t even think about reducing demand, say by reducing the all time record in migration. But that’s literally crimethink.

Sure the USA has a ton of empty space. But guess what, that’s because most people don’t want to live in those places. And the places where people do want to live like waterfront cities are geographically full.
