Yeah and it isn't just you accepting cash. Let's say you decide to go with cash (or, more realistically, manual bank transfers) and even get some host like 1984 that'd go to the court for you, but what stops Visa/MC to go directly at your host and tell them to either drop your site or they'll drop them?

In theory, if you went "full crypto", there's probably options like Filecoin and web3 domains (I'm not in that space enough to know what the current versions of these are) that could make something "uncensorable" by Visa/MC, but it also would limit its reach heavily.
