Nature is a complex system. Many are in competition, it's not just humans. Most of these systems form a balance (see biodiversity). Due to resource scarcity, power tends to form which gives these power structures and advantage. Humans form these power structures arounds groups. This has been happening for as long as humans tribalised. Right now, humans can form these groups at nation-state level complexity and to some extent more global. This is humans current best effort. If you can do better, please do.
