There are some surviving national circuits like PagoBancomat (as the sibling comment from Scrollone) and Dankort (Denmark) and girocard (Germany). My personal impression is that they are slowly going out of fashion in favor of visa/mastercard only (probably because they can’t offer better prices than them).
I don’t see a solution to the duopoly, apart from lobbying politicians to support this national payment infrastructure. Especially in recent times I can also see how some governments might not want to rely entirely on two US companies for running their entire economy, so something might move on that side, so there’s hope on that side.
The EU has already been moving on this front in the last years by forcing the banks to provide programming interfaces to initiate bank payments, and that’s why you can now see more and more options to “pay by bank” online in EU. These online payments generally skip card circuits and run over normal SEPA bank transfers.

The problem with the “it’ll go away at some point” is that the “at some point” might be much longer than what a few years.
This period feels to me like some “calm before the storm” or a “slow motion car crash”. We have AI possibly disrupting a lot of the service economy, while automation is slowly eating away the manual workers jobs, possibly resulting in mass unemployment. People are really fed up with politics and electing more and more nationalistic/extremist politicians because they don’t feel represented. The economical crysis and this dissatisfaction is an environment very similar to when hitler got elected. Last time we had millions of people dying and europe being destroyed, what will it take today to remove a dictatorship in the biggest military spender of the world? Who is going to save the US if it slides into dictatorship?
