The shriveling of policy-backed bureaucratic pretenses, perhaps? Revealing power's tendency toward private nodes?
I'd say it would be a sort of extremity of the nation-to-corporation transition. Pockets of private, military-grade power, without any omnipresent policy framework to hold them accountable. Unless, perhaps, it would be in their private interest to revitalize or sustain such policy frameworks.
It would be interesting to see what ideological residues persists, clinging to what bodies of power, after any such systemic collapse.
Am I correct in assuming that a post-government world is necessarily either post-collapse, or communism?
