If "The Cat" can delete the spam UTXOs then this is a game changer. Why would any node continue to store garbage forever on their computers if they don't have to? Freezing and deleting the spam dust is perfectly compatible with freedom of bitcoin. It isn't censorship and it isn't confiscation. It is choosing to no longer volunteer to have your resources exploited by shipcoiners and shit coiners. It is the obvious solution to this growing problem.
