I get that, as a system, less outbox relays (ie avoiding full replication to every relay) is important for scaling nostr.

But why should I, as a greedy individual that wants max censorship resistance for my own posts, not send my notes to hundreds of relays (assuming I have the bandwidth)? Clients can slowly send them out in the background without affecting my UX.

Are we building a system that relies on altruistic behaviour to scale?
