> The density is caused by people wanting to move to SF. High rises are a way to deal with the reality, not providing housing isn't going to solve the problem in any way people are going to be happy with.
Quite likely, just as many (if not more, in both absolute and proportional terms) people in SF will be unhappy with adoption of high-rises as the solution; the lack of availability under the current regime constrains some of the problems because it limits the ability of people to move in regardless of their desire to do so; relieving that constraint -- especially if the problems besides finding places to store the bodies aren't addressed -- just makes all the other problems of density worse.
