This seems like a ridiculous oversimplification for finding good alternative forms of government. A small community of people could come up with the greatest governmental system we could ever dream of, but if the leaders of the current system believe it to be a threat they could wipe out its adherents before it is ever properly understood by the wider population. Or spread misinformation about it to dissuade people from finding out more about it for themselves.
