Then she and other likeminded people should have organized politically and pressured the government to change the zoning laws before it was too late. Everything going on in the SFBA is the direct result of capitalism and democracy in action. I'm sorry if you don't like it, but I don't see any principled way you could object to it.

[UPDATE] Let me clarify: I can see how you could object to various aspects of our political system. I myself am active in trying to tackle the problem of income inequality and getting Citizens United repealed. But the housing problems in the SFBA are just symptoms of this much larger overlying problem. You can object to those, and I'll be right beside you. What I'm talking about is focusing on the high cost of housing in the SFBA in isolation as if it's a standalone problem that has a simple and obvious solution that the Powers That Be are just too dim to see or too corrupt to implement. That is not the case.
