you could, even though I disagree, use that argument for some artifacts, but surely not for the massive collection of things from Greece and Egypt. Those are pretty obvious you can return to the modern countries that sit on those lands.
Event if culture and religion has changed those artifacts are part of those peoples heritage, if it weren't then why would the UK care about Stonehenge or Hadrian's Wall? Or Italians about the Coliseum?
Just a single anecdotal point but I'm from Latin America and while there's little indigenous blood in me I would still consider indigenous culture and artifacts as part of my culture and that's at the extreme end of colonisation as natives were pretty much wiped out.
