I can jump a wall and break a door. What’s your point?
People leveraging the bitcoin protocol to become sovereign have no incentive to relay garbage around to other nodes and store that in their mempool.
That spammers can get around by tricking nodes into accepting spam or going directly to miners is not a reason for them start passing around spam.
Telling noderunners to just get on with the program and relay spam because it may end up in the chain anyway and gaslight them into thinking filters don’t work because they don’t stop every single spam txn is a hard sell and bad strategy.
