Money isn't a difficult concept? Tell that to the people of Turkey, on Venezuela, or Argentina. Ask them about the utility of money as a "store of value" or means of transaction. It can be mismanaged to disastrous effect.

Assuming you're in the US or EU, you have a privileged perspective: your currency is widely adopted and has been (relatively) stable. I think smaller countries (and especially the businesses therein) are better able to appreciate a global-by-default, noninflationary store of value they can use to transact with anyone, at an established rate.

You could cut Visa and other CC companies out of the loop: they'd be obsolete. Their functionality would be inherent in the network. That's huge savings, reduced complexity, and you don't have arbitrary companies with the ability to blackmail you.

Microtransactions online would become feasible, and would use the very same infrastructure as multi-billion-dollar global transactions. Nice and simple. No fax machines or SWIFT codes or intermediary banks. No reliance on banks with a monopoly on access to the financial system, that can pull a plug on a project at any time for any reason--or prevent interesting experiments from happening in the first place.

You know some places pay like 20+% fees on remittances? That's a shitload of money that the (relatively poor) destination countries badly need! There's a lot of gouging and rent-seeking that goes on in the economy (https://www.thebignewsletter.com/p/economic-termites-are-eve...), and a lot of it is enabled by the rigid, crufty and archaic financial system. A simple, open, global public system would fundamentally change that.

I dunno. Your attitude seems the same, to me, as somebody from 1994 who's happily using AOL to read the news, chat, and send emails (though only to other AOL members, of course) saying "What's the utility of this 'internet' thing? I can already do all that stuff! Networking is well-understood, and the 'internet' doesn't bring anything new to the table!" Their perspective on what was desirable or possible was strictly limited by the status quo. Just as was the case then, the best and most interesting use cases of cryptocurrency probably aren't even imagined yet: the infrastructure is necessary to imagine them.
