The problem is guessing what future rich beings value , that we have.
Who knows if Provenance of artifacts (art or otherwise) matters to non Westerners of the future ?
A non physical value have to be both non generatable and worth to curious alien super intelligent beings.
Antiquities have information that can’t be guessed and generated , and inform about the first natural intelligence being past.
Human minds before preservation is possible is an antique , an information ; even more then text or paintings.
Inherent evil is rooted in 2 sources.
1 Palatability is main source of inherent evil.
A fish inside water breath outside suffocating , a man the opposite.
Favorite food vs hated. Nutritional vs poisonous or allergic.
2 competition.
The enemy is enemy because what they do.
That is why inherent evil is a matter of perspective.
The sadist perspective is that the victim’s suffering is a good thing. If you like peanuts everyone (those who hate or allergic) ought to eat them. Jocker of mean jokes don’t see them as mean just the sharp point of the funny. Cats see the reaction of the pray as what they are doing right when practicing hunting. Falling from what someone judge as incompetent is funny , both as a show of dominance and not having in mind the suffering.
Homogeneity and competing for the same side , can take care of inherent evil.
