My entire point is that I reject this ridiculous premise. People who currently live in SF don't have any more of a "right to SF" than anybody else. Thinking otherwise is just plain old xenophobia.
The only land that you ever have an indefinite right to is land that you have purchased. I don't get "special privileges" to Seattle or Philadelphia just because I have rented in those two cities for the past 15 years. You don't have some sort of "special right" to your city either, unless you have seen fit to purchase property there.
