> Dont be shitty to people and listen to their voice are thing that any group of children playing may come up with them selves.

Not my experience at all. There's always a leader, and there's always a bully, and - if you're lucky - they are not the same kid. If you're unlucky, the whole group is a shitshow of gruesome sadism and "playing" that can lead to serious injury and death.

I mean, that's obviously anecdotal, but if children were so rational to invent things like human rights, why would we need caretakers and teachers?
