My point is that scale and speed of transaction doesn't seem to be VISA's problem.

VISA et. al. have scaled massively over the last 20 years, in ways that would have been unimaginable before.

Given that a VISA is just a 'number' with some 'info' on it, I don't see what any existential bottlenecks might be.

Maybe some things were centralized, but now are distributed ...

But given that each VISA is issued by a financial entity like a bank, which can manage it like any other account ... I just don't see the problem here.

I don't want to trounce creative thinking but most of this blockchains stuff is just academic for now.
