The hard part isn't processing payment... They already basically do that for themselves with the steam wallet.

The problem is getting the ability to withdraw funds from your customers' bank accounts. That requires a commercial relationship with your customer's bank and going through an insane amount of red tape. And there is no standard worldwide protocol for this, you'll be starting from zero in every market by cold-calling major banks.

The only viable approach is to have an army of salespeople, accountants, and project managers to do all those individual negotiations.

The EU has been trying for years to have an indigenous continent-wide payment processor. The first attempt failed, now Wero is poised to succeed in the next few years but that's building off negotiations that started a few years ago with pressure from the EU and buy-in from the financial sector, and still only a handful of European markets have been integrated at this point.

Now imagine all this difficulty but you have to also get active buy-in from every market worldwide. There's a reason Visa/MC have a near monopoly on international payments in the western world, and it's not that no-one else thought to get a piece of that very juicy pie that's making them literally billions in profit every year.
