In France following the French Revolution there was a period that is known as the "reign of terror" whereby revolutionary courts were set up to prosecute individuals who were believed to be "enemies of the revolution." This was essentially a witch hunt for the enemies of the political elites during this period.
In the House of Representatives, the election is made proportionally to the number of inhabitants living in each state. In this way, more populous states, like California, elect more representatives than states less populous like Hawaii.
In the Senate, the election is majority and two representatives are elected by each state. In this way, the interests of the states will be represented and defended on equal terms.
In this way, the 108th congress of the United States was represented by 100 senators and 435 deputies, respecting the demographic and proportional characteristics of the USA.
Although this question is opinionated, I believe that a government is absolutely mandatory to have a successful society. You simply cannot count on your citizens to agree on everything and all obey laws. It is human nature to want something for nothing, which is what laws are in place to prevent. You also would not have any form of protection such as a military, which means your society would get taken over by someone wot ha government very, very quickly. To put it short, yes, a government is 100% required.<span />
a) multipolar
According to International Relations Theory, a world where there is no hegemonic power and there are many regional poweres is considered multipolar: Thus, a regional power extends an area of influence and in global politics there is a clash of many powers that creates a multipolar structure. In this structures as we can see in the present every region in the world is determined by key actors that emerged from previous strutures and anarchy is less present in a international system.
For example in the present we see India become a powerful actor together with China, contesting US presence in the East Asia. As well the remergence of Russia with Vladimir Putin in European politics challenges a hegemonic power. And other key actors in South America like Brasil now contest in terms of economic and energetic powers. Therefore International relations theory analists would agree that today we live in a multipolar world.
