I'm confused by your nihilism. If the outcome is that I can get my money back (and I would argue that 250k covers a VAST majority of people, and then some), isn't that a fair trade for me not killing and eating a banker?
The fear is when it's just you.
I think a scenario where just a few million or whatever were effected you are correct. However if it was almost everyone, landlording would become a straight up mob. You'd have to employ violence and bypass the state to maintain the properties and enterprise. No one would rent out property the legal way if they couldn't collect the rents.
By the time it got to this another disaster already happened
