In both anthropology, and in psychology, cooperation, is part of our genetic make up.
Hell, you go into the race relations sub-forum, a good portion of the posts in that forum, are not based on logic, but on an emotive tribal basis.
Evolution, epigenetics and cooperation
Explanations for biological evolution in terms of changes in gene frequencies refer to outcomes rather than process. Integrating epigenetic studies with older evolutionary theories has drawn attention to the ways in which evolution occurs. Adaptation at the level of the gene is givingway to...

Genetics and developmental biology of cooperation
Despite essential progress towards understanding the evolution of cooperative behaviour, we still lack detailed knowledge about its underlying molecular mechanisms, genetic basis, evolutionary dynamics and ontogeny. An international workshop "Genetics and Development of Cooperation," organized...

It's long been a popular stereotype: Men are hugely competitive, meaning cooperative effort is the exception rather than the norm, while women have a tendency to nurture relationships with others, making them much more likely to cooperate with one another.

For example, if you study our closest relatives, the great apes, and how their tribes and groups within their tribal groups compete with each other, because of their large animal intellects, they depend on making intra-group cooperation integral to their survival. They depend upon one another for survival, it is part of their psychological and emotional make-up, as it is ours. We share a common ancestor in that regard.
Indeed, in the early stages or our development, in the tribal stages, and city-state stages, we could not have had, "pure individualism," those folks inclined to such, were banished from the tribe, village or city, and those genes perished.
Cooperation, is as natural to homo-sapiens, as it is to a herd of sheep.
Thus? Pure Libertarianism, is as much a pipe dream, as the various sorts of socialism and communism.
. . . it is impossible to escape, in the end, who we are. The global elites, would like to try though.
