You're right that I simplified heterogeneity, but my point wasn't so much that the preservation or destruction of culture should be left to a population of certain ownership--it's that these things should not be left to mercenaries hired by outsiders with a sense of global "human" entitlement.

Ownership and responsibility are really complex topics. The notion that you shouldn't rent a bunch of goons to steal books from your co-worker's house just because you think he's not taking care of them properly is not complex.
