one of the things that most people don't realise is that the reason why #nostr is built on a relay model, which requires people to run relays on computers that have inbound internet connections is because #p2p has failed because the mainstream of tech doesn't want users to be able to host data i dunno what the ratio is but something between 5 and 20% of nodes in a p2p network need to have inbound routing without that, it doesn't work and that's why we still have NAT and very few ISPs provide IPv6 addresses
