But they aren't getting their hands on dollars, they're getting their hands on crypto claiming to be tied to the dollar. Tether did the same - until they didn't. You can't be tied to the dollar without backing your coin with dollars. You can't possibly back your coin with sufficient dollars without US government approval. You aren't getting approval without following the same regulations as any other bank, which is what made getting dollars difficult in the first place.
Which means the only alternative is attempting to supersede the dollar by pegging to it but not actually being backed by it. Which, again, will never happen.
