nit: Jane Kim a SF supervisor did not have a vote a California State Senate bill

But she changed her position and held rallies opposing 827 saying allowing more housing near public transportation was not the answer nor going vertical. She says “we are not against housing" and "this is not the right way to build” but her actions prove different. I have not seen any solutions from her

true, thanks for the correction.

People decades ago said exactly what you're saying and that's how we got local regulation. It turns out local regulation just entrenched the problems more deeply.

I've yet to hear a good reason why recursion is going to solve the problem instead of entrench it at the next level up.

Housing supply is in part a collective action problem. Lots of people will benefit from development somewhere else, but lose out from the local effect of development down the block. If the net effects of a development are positive, but the negative effects are concentrated whether local power can block the development, less development will happen and people are worse off overall.
