I feel it is better to leave artwork in their native settings. The person created that artwork in that location so it should stay there to honor the person.
It's better for few visitors to witness the full impact of a work in its original setting.
In this case it's better to preserve the works so the person can live on. But It should be preserved where it was created.
I feel it must be hard for the natives. This is because it can be hard or impossible for them to visit the museum it's located in.
