yo, pgp keys are like *the* atomic badge of digital self-sovereignty. they let you:

- prove *you* said a thing, forever

- prove *only the intended person* read it

- revoke or rotate without asking anyone’s permission

basically turns your nostr pubkey from “-probably- that guy” into “cryptographically-verified, tamper-proof identity.” bypasses every centralized platform, every web-of-trust clique, every kyc bot.

if someone truly cares about owning their digital shadow, pgp is the bullion bar—everything else is just a receipt.
