There is a significant demand for housing in SF & the bay area. If housing is provided for free or even below market, demand will come from far & wide. Barrier-to-entry is basically a bus ticket.
Any real solution needs to at least attempt to balance supply & demand.
So let me ask you, which government obstructions would you like to see removed?
Seriously though, I was reading just yesterday about how they're developing Treasure Island and it has a high chance of liquefaction (not to mention radioactive waste) because demand for land is that high.
This was shortly after the plans for what would become the Transbay Transit Center[1], the Salesforce Tower and the Millennium Tower were approved.
Make your case though, why ditch earthquake restrictions?

However, I have to ask you about height restrictions. There's height restrictions because not everyone wants to live next to a skyscraper, which is well, debatable. I can debate both sides of that.
There's also height restrictions because the bedrock of San Francisco is not uniform across the city. In many areas of the city, I don't think you even can build skyscrapers and expect them to remain stable, as we are seeing with the Millennium Tower and the incomplete dome on the Salesforce Tower.
I could consider reducing height restrictions, certainly, but I don't think you can eliminate them completely.
In cities without rent control, like Seattle, development happens a lot quicker. Over the course of half a decade (2010-2015 IIRC) Seattle added more than twice the number of housing units as SF. Rent control's perverse system of incentives leads cities like SF to shoot themselves in the foot.
You probably could make a real nice camp on some dirt cheap woodland for 200 million.
Stack shipping containers 3 high, have one person live in each and have a shower block for every 15-30 residents. Cook cheap in large badges, get some teach for america out there to help them learn to read and write, require each person to spend a certain amount of hours working in exchange for food and housing...
The city wants to enable all of its homeless to escape homelessness.
It probably doesn't particularly want to house all of them, either directly (that is, the city itself) provides housing, or even have them housed within the geographic boundaries of the city. Having them acheive stable housing outside of the city would be just as much of a win.
