I think you're seriously underestimating the mindset gap between what Socrates, or any Greek citizen, believed about ethics and what we do. Even the famous stuff like the Crito reveals a completely alien notion of what the state is in peoples' lives. Furthermore, Plato, who actually wrote the character of Socrates, definitively didn't believe self government was best. He believed the poor and stupid should be ruled by a class of intelligent philosopher kings.
