He's saying that this affects far more legitimate users than sex traffickers by multiple orders of magnitude, while at the same time not preventing sex trafficking from taking place anyway.
No, no, we don't ban money, we just move to systems where the government gets to monitor all your financial transactions in real time and they get to selectively block those they don't find morally wholesome.
