Don't worry, the payment processors and corporate banks with federal charters simply will refuse to deal with them. They won't be able to buy services or connectivity. And then when they try to set up their own payment networks they'll be charged with trumped up KYC law infractions and put in prison.
Can't they still accept paper checks? I think banks are obligated to honor them. Groups like the KKK and the Daily Stormer have managed to stay in business.
