I would assume there would be arguments around transporting them increasing the chances of it breaking. It would really only make sense to move these back to their country of origin and have them remain there to minimize potential points of failure. The rarer the artifact itself (another rusted out sword or plain clay cup versus a one of a kind manuscript whose pages have become incredibly delicate) the less their respective owners are going to want it to be moved.

Instead, we should be allowing more people the ability to travel and take time to go explore other cultures in their country of origin instead of trying to transport priceless artifacts across the globe.

Fun fact: Many cultural artificats do go on tour!

For example I've seen both Pompeii & King Tutt exhibits in San Diego that have since rotated. I've also seen other traveling exhibits in several other major cities I've lived in that were far more than art.

Many cities also have free admission days to museums for people that live nearby (depends on the institution but it could be for City/County/State).

With this knowledge, you too, can now learn and explore societies that predate written word.
