I think you're having a hard time. Nobody said it's fully illegal, but does YouTube like to see people selling views? No, definitely not. It doesn't make it illegal, but YouTube could try to harm your business and this will probably be bad for you as a seller. The guy above is receiving BTC and Monero. Therefore I'd say that his project is more or less anonymous. There is probably never an investigation, but YouTube could still sue you. This doesn't necessarily harm your business, but it could hit the buyers as YouTube starts suspending︀ or stopping to pay or whatever. There's lots of legally built sites for buying views︁ with PayPal and credit card payment option. I wouldn't say it's totally safe to sell︂ views, but it shouldn't be a business full of risks. Obviously, still hard to get︃ bank accounts to support that.
What about VPN providers? Or mail︊ providers with stronger encryption than usual? Most of them have complex business setups or use︋ multiple countries, but there's also providers like Protonmail with crypto payment option. But I've still︌ seen a lot of other pro-privacy mail providers with no crypto payment option. It's a︍ risk thing I guess.
