Intentionally or not, Barlow evokes Marxism. We are creating a world that all may enter without privilege or prejudice accorded by race, economic power, military force, or station of birth. The only law that all our constituent cultures would generally recognize is the Golden Rule. They want to institute emotivism as the world's only ethical system because individuals who judge right from wrong via 'feelings' readily respond to being told how they should feel about things. Cyberspace, in its aspect of information as reality, the appearance of freedom from the actual world, could offer the shepherds a perfect stockyard for managing the world flock.
Constitutions represent theoretical expressions of a polity's practical political life.
To change a constitution, the practical political customs of a polity must change first. Before a world polity calls for a constitution applicable to the entire planet, the practical political life of every person of the world must reflect thinking in global terms. Declaring cyberspace free to develop its own political customs sans 'interference' from existing local polities thus represents a step toward developing a Cyberspace Constitution, applicable world-wide. Our Western Culture has dissolved and its remnant civilization begun to fade. A collectivized World State will leave little room for us to carve out our own havens of liberty.
