Fair - but encryption aside: nostr is specifically designed to avoid any P2P aspects.

For better or for worse the relay model is what defines nostr 🤷‍♂️ - we'll see if that pans out.

"It doesn't rely on any trusted central server, hence it is resilient; it is based on cryptographic keys and signatures, so it is tamperproof; **it does not rely on P2P techniques, and therefore it works.**" - https://github.com/nostr-protocol/nostr
