I respectfully disagree. I'm not a specialist in this subject but I don't consider living without a ruler fails to account for human nature, perhaps establish a community/society based on anarchy principles could not be done in large scale but for individuals and small communities it may be viable.

Large scale individual sovereignty is a contradiction in terms. You can only how small communities or individuals in anything. It is me?literally a mental illusion that a country exists in anything more than a mental exercise. You have nothing in common with anybody in your country besides a shared delusion. A Marylander has nothing in common with an Ohioan beside what we all share as humans.
