The complete dissolvement of all civillization, unfortunately, would be horrible. Sure, it sounds nice, at the moment. Perfect freedom, the ability to do what you want, when you want, and have perfect equality, in terms of obtaining something (Trade). But the problem is, how do we keep it that way? Over generations, it's bound that new Kings will rise, and lead people. More or less, making the entire world Chaos alignment just makes room for the Law alignment to shine.
