San Francisco could add a ton of housing without adding super tall skyscrapers across the city. Maybe some YIMBYs want to Manhattanize SF but certainly not all of them.

Paris has a height limit of 12 stories for most parts of the city https://www.archdaily.com/1002165/paris-reimposes-the-ban-on...

Hopefully the San Francisco BoS does their part and approves reasonable housing so it's not purely up to developers with SB 35/423.
