What if peace has never failed—only our systems have? For thousands of years, humanity has tried to govern itself through kings, empires, ideologies, and democracies—yet conflict persists. Homocracy and Digital Public Infrastructure exposes the hidden flaw shared by all traditional systems: the violation of individual free will. This book introduces Homocracy, a new model of governance where every human being is an equal shareholder, leadership is a service, and power cannot be centralized. Grounded in The Absolute Truth of Existence (TAToE) and enabled by modern Digital Public Infrastructure, Homocracy transforms governance from coercion into cooperation. Not a political manifesto. Not a utopia. A blueprint for a peaceful human civilization—engineered, not imagined.
