Nonsense. They're not insects, they're humans, and they've done just fine without any "courtesy" from the modern world. Such "courtesy" has klled off most tribes like them.
They want to be left alone - we should oblige.
That's exactly what I mean. They exist courtesy of our discretion. They exist today because charitable government authorities think they should be enabled to continue to exist, which is fine by me BTW. Otherwise they would be extinct. In the natural order of things, like predatory tribes, foreign military powers looking for forward bases, and wandering brigands, they already have declined, probably past the point of no return.
I know they are human beings, and they are being treated like an endangered species--eg of some rare moth in a terrarium. It's an analogy. Figure it out.
