What do you think will happen to the world without leaders like the President, Prime Ministers, King, Queen,etc.? I mean if we accused our leaders of being corrupt, oppressive and all other things, if they are not in the position, what will happen?
World without leaders is a very big problem. Without leaders, we don't know what to follow. We don't have rules to abide. Without the leaders, we don't know what will happen to our world. Without leaders, there won't be any progress or improvement in the world. Progress takes a leader and followers to work on.
World without leaders can be sustainable. Look at countries such as France and Germany. They are quite prosperous, although the leaders are quite incompetent and below par. Germany spent tens of billions of Euros of tax revenues to take in uneducated immigrants from the middle eastern nations such as Afghanistan, Syria and Iraq.
