Frankly, what's playing out in SF reminds me of what's playing out in US. Who has the right to determine how things stay? Outsiders or those who currently live there? Outsiders will like a slice of the pie and will cry and moan loudly about how insane and unfair it is, but hey, if you have a home, why should you watch your home value drop because of new apartments? If you just bought a home for $1mil just to be comfortable with no speculation and hope that it will grow faster than inflation. An influx of housing dropping your house to $800k will wipe out 100% of your down payment.
As an outsider, I feel for SF. I don't really care if they build an apartment or not. If I want to move there, I'll pay the price. What I care about is that they clean up, too many homeless, crazy, folks doing drugs in the public streets, poop, and all sorts of craziness. Clean that up.
