Should all the artifacts in the British Museum be returned?

It's trendy to single out the British Museum for some reason. But think about it a bit more, and you'll realize that the resources necessary to dig out, label, conserve, and then preserve (with the uninterrupted infrastructure heating, lighting, security, air conditioning and temperature control) a vast amount of material culture that is significant for our current and future civilization takes more then repatriating 'stuff'. There are important museums all around the world, not just the BM, all working to save fragile artifacts. And if there is an earthquake, terrorism, civil war, any kind of disaster, having items kept in safe places is important for generations of citizens globally. There are excellent museums that do this all over the world, world-class museums in Western Europe, North America, but also beyond: I've been to excellent museums of indigenous peoples in Mexico and Chile, and archaeological museums in Greece, Egypt, and India that also do this important work. So the BM is only one of a number of sites around the world, it just happens to have a huge collection (because, yes, empire, but wasn't the only empire). Tl;dr the work of cultural preservation is simply too important to simply 'send back', consider a more global perspective for future generations. Sorry if the above reads as patronizing, but as I get older I worry more and more about the loss of potentially significant cultural artifacts from around the world. Even the humblest clay pots tell us about trade routes, the levels of relative wealth of a group, what foods and drinks people had access to, etc etc. I'm not an archaeologist but I do find all this fascinating.
