Nah. Cause we human aren't good enough to live peacefully. If we get any chance, then Its our nature to take advantage from it cause people also have greed in their heart. And of course there'll be always some bad soul, who are born to brake the rules and regulations and got entertainment by violence, lazy people want to have others peice of bread by any cost , without working. So without any leaders, law and rules, it isn't possible to live happily in the world.
