I can't help but to see parallels between this "Money Service Business" applies to noncustodial services and The Pirate Bay's struggle against copyright trolls and, later, the Swedish State.

TPB also didn't host any illegal copyrighted content, they merely facilitated users sharing it beweem themselvs.

Samourai's Whirlpol, also didn't touch useers funds a merely passed message.

To me, we are fighting the same semantics
