I guess they "care about property rights" in the same sense that everyone right of die hard communists cares about property rights but that's kind of like saying it's a warm day out because it's 200-something degrees above absolute zero.

If they care so much about property rights then why is it so hard for people there to do build on their own property that increase the value of that property?

Saying SF cares about property rights is like when the person who creates drama says they don't like drama.
