> Not sure about what anyone here considers as libertarian, but if you were to ask a libertarian what they would tell you is that if you own property you are free to do as you please so long as you do not harm someone else.

I think that's why I'm surprised I don't hear that more. The size of someone's back yard or height of their fence (to a reasonable extent) seems like it wouldn't harm someone else, but they're strongly regulated in much of CA's single-family zoning.

> Also not sure what you mean by lefty orgs, because labor unions, public unions and environmental groups are the biggest lobbyist influence on the high price of housing.

Totally. There are tons of liberal orgs that are contributing to the housing shortage. I mean the few orgs I see advocating for development (eg SF YIMBY, or politicians like Scott Wiener) appear more liberal than libertarian.
