The theory of civilization is sound. It is the practicality of the thing that falls apart in application, every single time. It should work; maybe it even does for a time, but eventually it falls apart and regresses back to something barbaric.
Perhaps therein lies the cypher.
I respectfully suggest that you are using the wrong terms for the discussion: the question is more precisely stated, " Is organization artificial?" The answer is, clearly not. Single celled creatures organized into multi-cellular creatures by the natural process of evolution, salted with some chaos theory determinants. Animals organize into herds, colonies, hives, et alia, without artificial help. Humans organize in a lot of ways, and those organizations have pathologies, life cycles, and histories, analyzed at great length in sociology and org dynamics texts. Civilizations are organizations of organizations, and are no more likely to be immortal than any other work of nature.
