I mean net neutrality prevents the ISP one from being an issue, which means making the hosting provider should be the end of that.
The payment infrastructure doesn't really have a good solution. Visa/MasterCard are famously quite puritan, most sex workers (e.g. OnlyFans, porn actors) get paid in direct deposit (form the websites) and are paid (by clients) using bank details (not cards, nor in most cases paypal like processors, it's one reason Patreon toned down the sex work they allowed). So yes, one would have to do that, create your own bank and stuff. But banks, like Tier 1 networks, seem to generally "peer" with anyone, but I am not clear if that's a requirement of legislation or not.
