I would add a third which is allow more dangerous housing. You heard it. We all agree to risk, just a little more, we all die in a horrible fire so that the least among us have a better chance of owning a home through something other than charity.

What's the cheapest legal free standing residence in san francisco? I couldn't find anything under half a million. That's an easy 1/3 the price of any legal freestanding structure.
SF has both banned new SROs (flophouses) and made it illegal to tear down the old ones.
If we must live in a world where no one gives a fuck about the poor I honestly am not so sure they should be denied at least their slum house rather than freezing to death behind a dumpster.
