Even though it's generally pretty morally frowned upon, it's probably a high risk to damaging historical evidence that the pillagers may not consider "valuable" for resale in the process of finding things they do. It's also pretty much destruction and hoarding/privatization of literal historical artifacts, art theft on a chronologically heart breaking scale. Really we do largely want to touch those things. Just slowly and carefully and for the benefit of a larger volume of knowledge for the whole of humanity. "It belongs in a museum" may have some good debate around it, but "it belongs on the free market for the highest bidder" is probably statistically less favored, I'd wager.
