EDIT: One option I think you forgot is using one of the existing hosting providers but hide the web service under a TOR hidden service. That way people can't track it back to your hosting provider to complain about the hosted content (and you can use encryption of the content that is decrypted on the fly when being served by the web server) if you worry about the hosting provider doing some scans of customer content tho that seems very unlikely to me.
Make your own group: valid
Make your own site: valid
Make your own hosting provider: this one is tricky
Make your own ISP: shouldn't be needed
Make your own payment infrastructure: shouldn't be needed
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.
