Would that work with standard email though? I get that we could make it work amongst ourselves, but I'm thinking globally. Maybe not replacing for everyone, but "living on a Nostr standard" as they say in Bitcoin. Similar to Strike bill pay, etc, but for services that Nostr can reasonably replace. So when anyone emails me, it comes to a Nostr email client. I don't see how the two would be bridged. Seems like you'd still need an email server that forwards to a Nostr relay somehow. That's more complex in the short term it seems
