I am just now programming a system where you can make a temporary deactivation and a permanent deactivation of a user account. And a permanent deactivation is irreversible from the UI, though it can be reversed by flipping a boolean in the DB proper. It is intended for situations where, e.g., the employee leaves the corporation. Should there be an override in the UI? Why? The way you are stating it sounds like a mathematical axiom, but I would like to see it treated as a theorem: with a proof, or at least a powerful set of reasons. I can see that a particular person may rejoin the same corporation later, but IMHO they should be given a new account, not just have their old account reactivated. They aren't really "the same person" anymore, they might have a different job description etc.
