Controversial opinion: I think I'd much rather have a bloated UTXO set on my computer than any amount of child abuse jpegs.

Why are we all acting like op return spam is just going to be a bunch of silly monkeys, seems like it could very easily be stuff far more offensive and damaging. Try telling people they just have to download and store a few CP jpegs on their computer to be a fully sovereign bitcoiner, see how well that goes over.
