I don't think the head can really be separated from the nervous system, nor even from the external feedback of the outside reality which has formed and evolved its senses. To say it's "all in the head," would be like saying the internet is all in your computer.

Similarly government is an organic response of group hierarchies that has been formalized. Its evolution is deeply tied to the evolution of religion as well.

I think there are two basic dynamics to reality; Synchronization, which is centripetal and harmonization, which is centrifugal. So nodes and networks, organisms and ecosystems.

As such, government, as well as the nervous system, is about synchronizing actions and the effect is centripetal, drawing energy to a focused effort. That's why governments like enemies, or at least external goals to focus on. Flora are better designed to simply grow in place.

While the circulation system is about distributing energy effectively across the entire organism. Yet the way our financial system has evolved, it's more like a tumor sucking vital resources out of the rest of the body.

I suspect that when future historians look back, they will see this stage of social evolution as when private banking cooked its own goose. It's having its, "let them eat cake," moment.

Though it will take a fairly hard landing for humanity to understand the basis of society is responsibility and rights are a reward. The effect of a society based on rights, with responsibilities being left to churches and families is the tragedy of the commons. Where nothing is cared for and everyone takes what they can.

Everything that has a beginning, has an end. It's a matter of how fast you burn the candle and how well the environment can absorb the waste.
