I learned a long time ago that the most effective way to correct a vice is to play it against another vice, sloth being an easy goto. But in this case... I'm not a drug dealer, so I don't need to launder large amounts of small bills. But... if I wanted to launder a bunch of public ledger based crypto: instead of a using a loud and proud "bitcoin tumbler", I'd use something like satoshibet. Of course, that is likely why the original no longer exists - and I imagine anyone standing up a replacement (without a sufficiently invasive KYC implementation) would face similar hostility. Anyway, I expect that'll change when a state run satoshibet eventually emerges.
