Any examination of sociology, anthropology, and history shows a rich, long history of humans helping each other through peril, banding together in the toughest of times, and cooperating. It is by far our most recognizable trait as a species, and it appears in isolation whenever humans are together. I do not buy that there is some primitive animal culture that we will revert to if the Internet went down. There are humans who have never experienced "civilization", and they do not live in chaos and evil so I don't buy your argument at all.
