That's not true, at least not in general. Polygon (and USDT/USDC on Polygon) fees are near zero, Ethereum is lately very cheap, and even Bitcoin fees are no longer outrageous. EDIT: ...and Bitcoin Lightning is cheap.

A lot of p0rn payment processing is done in crypto for exactly the censorship reasons. If you can't use the payment processor, who cares what their fees are? (not saying they are cheaper or more expensive than crypto - I don't know)
