i think it's important to acknowledge that the reason why mastercard/visa has such a stranglehold on american society is because cash is not the main form of payment in the usa. the predominance of card has effectively privatized currency
in japan, one of the reasons why dlsite and other similar websites are able to just remove visa as a payment option instead of changing any of their merchandise (aside from the fact that visa doesn't have a monopoly here) is because cash payments for online transactions remain an option. even if you don't have a jcb credit card or paypay or whatever, you can still pay for your online purchases using cash by taking your barcode to a convenience store, and you can do this for essentially every online vendor, meaning credit card companies can't just impose their moral judgments on your purchases with much repercussion
How does that barcode system work? I've never heard of something like that.
1. you add whatever porn games or movies or books you want to your cart and go to checkout
2. you select cash payment at conbini as your payment method
3. youre emailed a barcode that you take to the conbini
4. you show it to the cashier, they scan it, and you pay what you owe. note that the cashier does not see what youre buying
and the transaction is complete
