Correct me if I'm wrong, but it's a bit heavier than that if technically identical: the coins cease to exist until 51% of miners come together again to declare that they should exist again. At which time they also might agree to pay themselves any amount of Dogecoin or flood the market.

I bring this up purely because "ban is lifted" sounds like a much more achievable thing than I believed was possible. While 51% of people might agree to blacklist some obviously illegitimate coins that harm the value of the market... it doesn't implicitly mean that they would come together again even if irrefutable evidence proved their original belief wrong.
