> Would you return items to a place incapable of taking care of them?
Isn't this like saying "I'm not going to return what I stole because you clearly aren't capable of taking care of it, if you are it would never have been stolen"
I think there's a misunderstanding about the intention behind asking for return of stolen artifacts. It's not aleays about the artifacts themselves or how valuable they are or preserving them at all.
Returning items is like acknowledgment of historical mistakes and a signal that the other party is ready to make amends.
Merely acknowledging the mistake while holding onto the stolen artifacts is just a lip service that isn't even sincere.
