Society has a variety of ways to entitle people to live somewhere. One involves purchasing the property. You could also enter into a lease with your landlord that gives you the right to renew for a very, very long time (which you'll pay for, of course, if you get it.)

Now, if you want to talk about rising property taxes driving people out, that's a legit thing to talk about, but really more of a NYC problem than SF.
