Take Los Angeles where the median home is 900k now, homes sell like lightning, and you move into your apartment the week after you tour it because it's that competitive. There is demand to live here and has been forever, basically, probably always will given that's how it goes for large American cities. It is baffling how backwards the land use is.
It shouldn't be possible for a lot zoned for mixed use commercial and residential could sit as a derelict burned out building for years(1). It was burned out recently, but street view from 2007 shows it's been abandoned for at least 14 years now. This metro station takes you either to hollywood or downtown LA in 10 minutes, massive job centers as well as nightlife areas. Anything built here would get signed leases that week, just like everything else in Koreatown. Other notable pieces of land use for this corner precious steps from the metro station are a gas station, an abandoned hyundai dealership, and a drive thru offering unhealthy food to the community.
If someone quantified all the externalities, I'm sure poor land use alone causes trillions in economic and ecological damage to our cities in this country. This is our hardest problem.
