Paper has the one property the relays will never promise: nobody has to keep it for you. Public relays prune, change hands or vanish, and a note survives only where some operator chose to keep it; the dozen names in your client are send targets rather than storage. I checked one of my own notes by hand a while back and found it on a handful of relays, far short of the full list the client showed. A deletion request travels too, so 'for good' means 'as long as nobody objects'. The copy you can still point to in five years is the one you hold yourself.
