alt Hacker NewsIf demand picks up because supply increases, you will reach the previous equilibrium even with more supply. It isn’t rocket science, there is a price people are willing to pay to live in SD, and the market will keep gravitating to that price unless demand is somehow limited. The price people are willing to pay can even increase as density makes brings in things (eg culture, job opportunities) that make the city more desirable (eg see Hong Kong).

There a lot of desirable areas in a country and a fixed amount of people.
The equilibrium between demand and supply has the supply curve impacted by a whole host of policy choices.
Eg housing is impacted by cost of permitting, regulations, cost of materials and labor etc.
All of these things can be improved by policy.
There's a strong argument that especially infrastructure but housing should be built with people on work visas.
No, this is a false belief known as supply skepticism: https://scholar.google.com/scholar?hl=en&as_sdt=0%2C5&q=supp...
At the levels of density seen in Paris, San Diego could house 16 million people. That's city proper. The metro area could house 226 million people.
You're gonna have to do a lot better job convincing me that 16 million people would move to San Diego if they just built more housing. Let alone 226 million.
