I believe that cryptography and decentralization beats federalization and ICANN domain names as an end goal to a more decentralized internet. There’s already bridges between activity pub and nostr and they seem to play nice together. I can imagine a world in which it’s almost seamless between two or three decentralized & federated protocols.
And to those that are upset that a few relays ask for or require crypto transactions, keep in mind that some mastodon/lemmy/activity pub servers demand payment and I’d be hard pressed to find one that doesn’t accepted crypto donations.
