This. I would also add that renters with such strong rights as they have in SF also constitute a mutex on a property. When so many of the units have these mutexes, it makes it basically impossible to develop property in San Francisco. The other policies such as minimum parking requirements, CEQA lawsuits and "you'll block my view" lawsuits, etc. are all basically mutexes on a property held by everyone but the property owner, which is the only person with an incentive to develop their property for profit. And by "develop" I mean build more housing that would help alleviate the shortage.
