Cryptocurrency is the only way I see this working.
Cryptocurrency is a nice idea but there are and have always been too many gas fees for anyone to sensibly use it. I want to buy something not support everyone that get their hands in my transaction chain. The US government can break up the duopoly and open up payments processing federally. That’s worth the investment than that pipe dream of a global, frictionless cryptocurrency.
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)
