I thought about this question when it comes to Anarchy.
How long would it take for majority to adapt to anarchy, that is start to follow rational non-aggresive principles. And majority of the destructive forces to be forced out of market by consumer choise?
That is if we were to start now?
According to Merriam-Webster Online, anarchy is "a situation of confusion and wild behavior in which the people in a country, group, organization, etc., are not controlled by rules or laws"
By that definition, I feel like it would be impossible to call a working thing "anarchy."
