"Oh we cannot filter stuff from Bitcoin because it will be a slippery slope and in no time we are going to be OFAC compliant" - this is a decentralized censorship resistant protocol, you as a node runner decide what to run. There is no slippery slope, the devs or gov can wake up tomorrow and put an OFAC compliant node and force miners to run it, then what? you don't run that version, you choose to relay those txs and hopefully a miner in other jurisdiction mines it.
