People conflate your identity with your keys. Your identity is you. Your keys simply hold a history of your comments. They are not your identity. Just a temporary verifiable proxy for it.

You can have as many keys as you want. That might represent one or more of your identities.

Stop thinking Nostr keys are forever. They are not.

Stop thinking they are you. They are not.

Stop thinking you need to bundle everything in just one key. You should not do that.

Stop thinking people follow your identity. They don't. They follow one of your keys.
