Put another way, humans develop hierarchical governance as soon as their group grows beyond a couple dozen. Even if you look at corporations, internally they're structured like governments.
Most corporations are structured like ultra-authoritarian dictatorships. I'm not sure you want to use them as examplars of human governance.
Why not? They're perfect examples of efficient governance. We don't like to have that efficient governments, because in politics-land, this often involves bloodshed and suffering.
