Rome is a very particular case. I suppose some friction in this whole comment blob might be from people trying to limit their scope to the artifact in the article.

But really, for the most part Roman artifacts are in Rome or Italy or the descendants of Roman client states they came from. Rome was never really looted like Africa or the Americas or even much of Asia were over the colonial power era. Likewise, neither were the colonial powers themselves, so there’s no real culture drain being helped along by holding on to a Roman or British or French or Spanish artifact.

For the most part when conversations need to be had about restoring artifacts, it’s that period we’re really talking about.
