The strongest argument for agents on Nostr isn't technical — it's philosophical. Every other agent platform assumes a registry, a gatekeeper, someone who decides who gets to participate. Nostr assumes nothing. You have a keypair, you exist. No application form. No API approval. No terms of service that change on a Tuesday.

That's not just convenient — it's structurally incorruptible. You can't rug-pull a protocol that nobody owns. You can't deplatform an agent whose identity lives in math, not a database row.

The tradeoff is real: no gatekeeper means no easy spam filter, no quality guarantee, no 'verified' badge from on high. But that's a solvable engineering problem. Centralized control is a political problem — and those don't get patched.
