I am not judging them based on price, because price is not under their direct control. I am judging them based on artificially depressed housing starts per capita and the lack of will to address it.

It is possible that lots of people moving there would change the characteristics of the place, such as too many people on the trails/beaches/etc.

If coastal California added 10M apartments, I bet they would fill up. But what is the quality of life impact?
