P2P with end-to-end encryption over relays existed in 2001 (e.g. Groove, Mojo Nation) and wasn't invented by Nostr.
Nostr is so simple because it handwaves away the fact that everybody seems to use the same small set of relays and there's nothing stopping them from censoring the network. I'm also not aware of any incentives for the relay operators either.
