Tbh that's quite alarming what you've just said, and I'm not saying about government. I'm saying about an additional huge sales tax. I understand that wiring money or sending them in an envelope is the thing of past, but e.g. in my country and in whole EU the digital payment is promoted as the only righteous, because "cash is only used by gangsters and human traffickers" etc. And this is really playing against us and pushing us to the duopoly you've mentioned
Credit cards are much less heavily relied on in Europe than in the USA. Europe basically runs on debit cards that every kid can have and where the fees are minuscule. There are countless banks providing the service and everything is highly regulated. On top of that, Europe still curbed Visa and Mastercard several times for antitrust behaviour. And the idea that physical money primarily aids social fraud, money laundering and other illegal activities is pretty well established. They even killed the 500€ bank note, because it was almost exclusively used by criminals and most normal people never even touched one, much less used one for legit transactions.
