I think there is a little bit of a "Prime Directive" at play (which may be a rehashing of your thesis). Uncontacted peoples are also highly sought by researchers for scientific investigation (which human traits are due to our culture and which aren’t?). There’s also the reality that economic interests may eventually force the issue and these people may be "relocated" to support mining, logging, fishing.

Yes, the description of the linked video mentions the tribe is being encroached upon by logging interests, so this entire conversation is moot. Capitalism will kill them soon enough, either through assimilation or extermination.
