I don’t understand this binary. The UK was able to create a near-instant bank transfer system without monopolizing in the same way. https://en.m.wikipedia.org/wiki/Faster_Payments

It costing more for instant transfers is just a regressive tax on the working poor.

I can't find the details of the UK system, but it's not "monopolized" in Brazil. Perhaps due to the fact that the infra is provided by the Central Bank, and banks choosing to implement Pix support must implement the Pix APIs in their system.

Everybody adopting an open protocol is "monopolizing" now...
