> For me, my one and only use of crypto (back in the day) was to put it through a mixer and then use it to pay for hosting for some TOR exit nodes in Iceland that I didn't want tied to me personally.
That use case at least makes some sense and isn't illegal, but there are probably only dozens of users who'd ever want to do something like that, which isn't enough to support a payment ecosystem.
There are also probably conventional alternatives that probably work for that. I'm somewhat paranoid about getting doxxed based on some teenage internet experiences. There are a couple of forums out there with paywalls that exist mainly to reduce moderator workload, and (10-15) years ago I was able to subscribe with a combination of Visa gift cards and PayPal. The gift cards let you enter (un-validated) identity information so they could be used like credit cards online, and PayPal didn't seem to like them but there was a long delay before they were detected. So I created a throwaway PayPal account with a small-denomination gift card as a payment source, paid for the membership, and abandoned the PayPal account (which would eventually get locked).
