You don't have to relay spam, it's your own choice. Same as miners who include harmful arbitrary data. Common sense will prevail, belive in the good!

We need to stop hoping people like Peter Todd will make good choices on our behalf. There must be a way for consensus to be the standard.
I don't get your point? A miner decides what goes into the chain, and nodes influence what TX reach miners through the public peer to peer network. The goal is not to censor illicit arbitrary data TX but to rate limit them such that it's severely dissincentvised to do them.
A few bad actors with open filters won't be a problem. The occasional garbage TX will be mind, but that's okay.
