"I'm going shopping, can you get me the shopping list please?"
*goes and fetches a piece of paper from the kitchen*
"Wait, this isn't the right list! This one has more things on it!"

The question of whether or not the thing fetched is indeed the
shopping list is independent of the items on it. The list has an
identity and it has a value (the items needed). If I hand you an empty
list on the basis that the shopping list you placed there last week
was empty, I've destroyed the value of the posted shopping list -
people have added things to it during the week, and they expect those
things to be on the list that gets referenced to make purchases.
