So what sort of mechanisms should zkSNACKs put in place to defend these victims from these criminals?
Nothing? A coordinator is not a policeman nor a jury?
Bisq uses trusted third parties who escrow, it's not self-custodial.
Not self-custodial, but it minimizes trust. Anyway, my point is that your previous citing of the whitepaper is completely flawed, because Satoshi meant that most benefits are lost if electronic money requires a third party to
prevent double-spending. It does not apply on everything indefinitely, and centralized exchanges are a perfect example.
Hey BlackHatCoiner, my wallet is now a "mixing site" service, send me your coins and I won't charge you any fees.
"Yes, BHC, people do choose to forfeit their custody in exchange for this service, but I refuse to ever accept this reality."
