Every time this comes up I just can't escape the notion that it's really just because SF, geographically and culturally, has more desirable traits than other places. Temperate climate year round, travel hub, diverse thought, tech opportunity, walkable. What else has this? More people want to live there than it can handle. Build more housing, perhaps the price drops for the people who are there, but then that price will mean more people will want to move there. Wouldn't it be better to have another high quality population mecca nearby? It's the same with homeless policy - if you make it attractive enough, you attract more homeless, unless surrounding areas have also implemented similar homeless policies. Building more housing is a supply-side argument - what are some positive ways to reduce demand to move to SF?
