And yet people love it and want to call it home, and are willing to make sacrifices to do so. I know I have here in the Seattle area. Mind ya own business!
So maybe not everyone who wants to live there gets to.
Again, not from out that familiar with the area so maybe I’m off the mark here.
So instead of SF continuing to expand to engulf all of California, other cities in other areas would begin to grow. Somewhat this has happened - Redmond near Seattle, etc, but we haven't really had any "ground up" new cities that I can recall, they're all offshoots/suburbs of existing ones.
