You could 10x the density around there and be able to support the population. You’ve got wide streets, services, and it isn’t landfill.
Honestly though, I feel like it isn’t really a crisis. It’s mostly rich people fighting with other rich people over whose backyard to build in. There are no real YIMBYs, just people who want to live in certain areas they don’t currently live in.
Most of the poors have already been displaced. We pretend like they are the focus because it’s good for politics, but the reality is the diversity is already gone.
