It has to be auditable from a supply standpoint. Anyone should be able to verify supply. I think privacy happens at the transaction point like with eCash, or at the wallet level, like every wallet is built-in coinjoin. Or we just decentralize the shit out of coinjoin services so there are hundreds of options so the baddies are overwhelmed (same goal as the former). Unfortunately I don't know enough about the technical stuff to form an ideal situation. But if ANY questions of supply exist it's all fucked I think.
