Nothing I posted was to scare anyone. It was to point out how things are going to go down, sooner or later. There is no magic wand to make OP's child's mess go away. They need to start planning how to address it.
I take that back since we are talking about California. There is a magic wand. The state could try to pass a law erasing rent entirely during the crisis. It would just pass the economic devastation on to a different set of people but they could try. I would imagine it wouldn't survive a court challenge.
