Heh, and intra-crypto wars like this are one of the reasons the Trust Problem hasn't been cracked yet. People are too busy trying to fix the part that's already solved!

I mean, look. Yes, there are ways to trace bitcoin et. al. given some level of sophistication. But the threat model isn't an intelligence agency trying to unmask a single porn consumer or cam worker. These technologies are "anonymous enough" so that an outfit like OnlyFans can reliably take payment from arbitrary consumers without fear of regulatory interference. This part really is solved. It's just not enough.
