Possibly but I don't think it has to be. I just think it's an optics / branding thing. Like if I said to a new artist 'hey download this app and I can easily send you money for your music'. And they downloaded Primal and set up the wallet. And they saw a dollar land in their wallet when I zapped them. That would freak them out less and leave them with less questions than if it was bitcoin. Then I said, upload your music here with this lightning address and tell your fans they can support you on Fountain with apple pay (also denominated in fiat) they don't even have to know they're using bitcoin or nostr, it all just works.
