Real life arriving does not change what Nostr stores, only who is reading it. A note gets copied to every relay that picked it up, and a delete request is just another event that some relays honor and others ignore. So the reset is a new keypair, and the price is the whole follow graph. A split that holds up: one key for the people who know your face, one for the open timeline, kept apart. The leak is never the obvious one. Same zap address, same photo, a phrase you always use. One overlap links the two, and after that there was never a wall.
