No, but surely you recognize that if not for being kept safe in the UK all this time these heritage items would simply have been looted, sold, or destroyed. There are many, many examples of treasures lost forever in this way. Yes, these pieces originated in certain countries. But they are also a part of collective human history given how old they are. Hell, some of these places are still chaotic enough that if you returned them they might face the same fate.
