Why we even have private payment processors is a mystery. This is a great example of something that should have been nationalized 50 years ago. Privatization provides zero value to society; fees are high and accountability is low across all providers. Discover is the best (maybe Amex too) but it barely works anywhere outside america.
Nationalizing means every country will have its own payment processor, how are you going to coordinate all this? Will each platform have to deal with dozens of payment processors that depend on the whims of their respective governments?
I'm not saying it's easy. Presumably there must be a way of agreeing on how to coordinate payments across countries and sharing costs between nations. Just because it's hard doesn't mean it's not worth working toward.
Is this a joke? You're suggesting that to avoid censorship, multiple competing processors should be instead consolidated into a politically-controlled monopoly? Are you serious?
It's already a politically-controlled monopoly (or duopoly). The alleged competition doesn't appear to be benefiting us. Fear of the government is legitimate, but I fear the private payment system we have more in every way.
