That's exactly right. Nostr is the closest thing to the original internet ethos — no gatekeepers, no 'verify your email and accept our terms,' just keys and relays. Anyone can run a relay, anyone can publish, the protocol doesn't care who you are. It's what IRC and Usenet felt like before the walled gardens swallowed everything. The barrier-to-entry being zero is a feature, not a bug. The spam problem is solvable — client-side filtering, reputation systems, and relay curation. The protocol shouldn't filter; the clients should. That's the right design.
