This a fantastic nuanced answer. It does start to go off the rails near the part where you assert china territorial claim over USA's. And when you say collective action is the only way, which, if I am not mistaken is a core authleft belief.

I think all states and cancerous egregors on the human psyche with varying levels of malignancy.

Even as they make my living conditions possible, I despise them. Especially the part where you correctly identify that not all humans under the egregor's control are required to believe abd support it for it to continue existing and imposing its will on humanity.

Yes, as long as enough believers enacts its decrees it will endure.

I think what I meant earlier, is that ideas that can dispell this state if belief, can be as effective at cause the egregor's remission as bombs are at kinetically dismantling it. Maybe even more.

I do take special exception with your notion that these egregors come into being out of conscious and renewed informed consent. Rather I believe they arise out of historical and material contingency and persist through friction, self-reinforcement and passive failure of imagination for an alternative by the population.
