Why should the government buy them instead of providing the grounds for private party to access the real estate and do it themselves? Where do you draw the line? Should the government continue to push companies to fail so they can buy more land until they own it all? I’m low income and I work hard to afford living in SF and I don’t agree with having to pay even higher taxes for the government to waste 80% of that on bureaucracy and 20% in housing. I agree with you in that they shouldn’t bail anyone out, but I think they should just operate in their realm: zoning, code and incentives to entice the change to residential.
