Hmm, it seems like you've forgotten Detroit's history. Why it became your go-to example for a failed city.

How many low income people can afford to live in SF now? Not many at all. There would be vast amounts of cheaper housing if there weren't artificial constraints imposed.

No argument from me on that score. ...nor even that SF political culture lead to the current state.

But getting rid of artificial housing constraints is a far cry from saying: how dare non-rich people even think they should be able to live somewhere with good economic opportunities and a high quality of life.
