I agree. Most of these tombs are better in the ground, unknown and undiscovered. I understand we can build knowledge from these artifacts, but there may be some unforeseen value in abiding by the benign wishes of ancient peoples.

I don't trust modern society to store these artifacts for more than a few hundred years without losing them to war, theft, modification, infrastructure issues, or whatever. The modern world is relatively unpredictable and chaotic compared to the past, in my mortal opinion.

That said, it's nice to have some of these out of the ground, for us still living. But pulling up everything we find feels like science-sponsored grave robbing to stock our treasury of knowledge, which is valuable but not holy.
