The issue of "this is a convenient thing to think if you want to feel less bad about stuff being stolen" aside, it's worth considering that a world in which these things weren't stolen might also be a world where colonialism didn't run rampant throughout the world and the "destruction" they were saved from may have been a consequence of that colonialism.

Anyways, I think to some extent our civilization is descending into a kind of mass packrat disorder. We seem to fetishize preservation to an unhealthy degree on both small and large scales. Sometimes things break, are burnt down, or are left unmaintained until they die. But new things are created all the time, and maybe sometimes we get a little too stuck on the old stuff and don't acknowledge the new.
