I think you've nailed a problem with all of these, they would make "deleting your stuff" HARDER. What's stopping the rogue node from saving all your stuff forever?
I think "trying to make a thing that can work through rogue or stupid nodes" is just prohibitively harder than "work on making nodes more reliable" (which I absolutely grant is extremely hard.)

Nothing. You must always have this in mind when posting online: It's impossible to ensure that data is deleted and gone forever.
