This is the rat race. You are competing with all the other humans around you in the same playspace of reality.
A mortgage is a loan that gives you money you don't have (yet). If you are spending money you don't have, do it wisely or suffer the consequences.
I think no special treatment. Everyone else in the same space has the same rules/uncertainty as every argument you offered.
These are my feelings too, but in the interests of compassion, I would suggest a return of some proportion of equity to (human, non-LLC, non-corporate, primary resident) buyers in cash, up to bank failure. Hopefully they can then buy another house at the presumably much lower prevailing market rate. Someone has to lose, let it be in order of "he who should have known what he was doing in making this catastrophe possible."
