Perhaps not necessarily in this case, but something I do think about is, are not certain artifacts safer in the museums that can take care of them for future generations? There are many unstable countries in the world where that cannot happen, and I would want artifacts not destroyed due to wars or other sorts of fighting such as terrorism [0] such that future generations can see them. That is why I am not necessarily opposed to so called colonial governments continuing to hold on to relics, as the British Museum has stated.
