The same issue arises over and over. Like the destruction of antiquities by religious radicals in Iraq and Afghanistan.

It's good to round up antiquities at risk and export them, but with the right provenance and to suitable institutions to hold with a public display of that provenance, so that when an appropriate time comes, they can be returned. I.e. treat it as "borrowing" or "safe-keeping".

Not just take it and sell it to unscrupulous buyers who will keep it.

How would you like it if someone swooped down on your house in advance of a hurricane and said "hey, your house is going to get destroyed anyway; why don't I take your appliances and electronics and sell them to other interested parties for my profit? After all, you won't be able to use them while you don't have a home, so what's the harm?"
