Not really - there don't exist any digital currencies that A) have desirable economic/security properties B) can scale to billions of users and C) have a UX that's accessible to unsophisticated users.
Visa's role in a Bitcoin-based economy is probably providing custodial wallets, Lightning payment routing, etc.
> the ability to transfer ... should be a fundamental right and core function of government
The government has historically done a pretty bad job of this (which is why 99.9% of consumer payments go through private systems).
Why would I want the government to manage this when we know how to do this well without a government involved? What's the benefit of using FedCoin over using something decentralized with good monetary properties?
> I think for government to stay relevant then it needs to start to encompass more distributed protocols. To the degree that it fails to do so then I think it loses relevance.
This is an oxymoron - if a protocol is distributed, it inherently obviates the need for governmental management.
