Okay, I'll say it: is it really worth encumbering the movements of millions of people for decades in order to make a few boring history exhibits? If you want to see some the bone comb that belonged to somebody's great^100-grandmother, there are dozens of museums that already have one on display.
They might find some important writing that can shed light on history.
Yes. I travel around the world looking for such things.
Is it encumbering? It seems like it's not at all.
Is it really worth? YMMV, but yes if you ask me.
The problem isn’t the present tense. The problem is once those artefacts are destroyed then they’re destroyed forever.
