If Nostr is to become popular & widely used, then the people using the protocol will have the say on how it functions. Majority rules.

Permanency is part of life… we cannot undo our actions or words, but we can mature, cultivate & better ourselves. If a snippet of our unsavoury past is taken out of context, such as for a Nostr post, then it does not tell then entire narrative. And it’s that snippet narrative that we couldn’t delete that becomes the front-row-centre issue.
