It's bizarre considering that with limited exceptions (mostly descendants of the Ohlone), everyone in San Francisco is an immigrant going back several generations. San Francisco appears to be a city that thrives on immigration and new arrivals, so perhaps the people getting upset about it now are just a tiny but noisy minority?
The surface of the SF area is limited and almost already at its full capacity. It is a resource.
Either you let the market do, and the price will logically higher, or an authority will decide who can stay.
In first case, Techies are indeed provoking the eviction of long time inhabitants, on the other hand how do you decide those who leave, those who stay?
You choose the people contributing the most to the economy, or the one that relatively are bringing nothing but cost? (fireman, under-educated workforce, public services (trashs...), policemen....)
Well, let's hope techies will learn how to do all these underqualified/cost sink jobs when these people won't be able to afford any more housing.
The problem in SF isn't that we couldn't build up more - we certainly could. It's that you generally have to tear something down to build something up,. I live in one of the less fashionable parts of SF that is zoned single family, though it is somewhat dense by American standards (small lots, no space between houses, though each house does have a small backyard). Most of the houses were built in the 1920s and are in my opinion architecturally interesting, though of course opinions will vary. I suppose we could allow people to buy up a block or a bunch of houses, tear them down, and replace them with 6 story (or higher) apartment buildings.
While there is a case to be made for allowing this, I think it's probably the weakest place to make your stand against the lack of new housing construction in the bay area. We have options other than tearing down some of the oldest neighborhoods west of the mississippi.
While everyone may be saying Not In My Backyard, there are degrees of NIMBYism. Personally, I think that it's far more egregious for very low density areas like Mountain View or Menlo Park to ban new housing development, especially when these are the same cities that have green lighted office construction that will bring hundreds of thousands of new workers to the region.
Four stories? Wow, even the "historic downtown" part of my city is zoned for 5 stories, and they explicitly keep the roofs low so you can see the dome of the capitol building from anywhere in downtown. https://en.wikipedia.org/wiki/Concord,_New_Hampshire#mediavi...
Paris, New York, and Hong Kong are all in very low earthquake risk areas though. I imagine people were sensitive in San Francisco after the 1906 earthquake destroyed most of the city.
That said, Tokyo shows how it can be done, but to replicate Tokyo in San Francisco would require tearing down and rebuilding a lot of existing housing stock which would temporarily make things even worse.
