What does this mean? If a single blacklisted coin is put in a mixer then every other coin mixed together is blacklisted? You've just banned mixers. Eventually every single coin will be able to be traced back to a blacklisted wallet, so you've also just effectively banned crypto in the long run.

> No legal entity would be able to hold or trade blacklisted coins.

Mixers don't have to be entities though. No one owns them, no one is responsible for them. They're just code someone uploaded one day and promptly forgot about.
