You’re the one who is naive. Spam will always morph and find its way onto the chain if it’s affordable to do so. To think you can stop it with perpetual changes to the protocol is a reactive losing game and it’s the naive way of thinking.

Let go. Stop being emotional and stupid. Fees will price out spam eventually. If in the interim the spammers leave a bunch of huge stupid unspendable multisig scars on the chains that’s a much worse outcome than spendable UTXOs.
