What is the pupose of government? Does politics support or impede that purpose?

According to American Government: Power and Purpose, Government can be defined as "the institutions and procedures through which a land and its people are ruled" (p.5). While the country we live in is a democratic republic, there are many other types including oligarchies,monarchies, authoritarian governments, etc. Even though there are many forms of government, one might wonder why we have government at all. The primary reason is simple a government is needed to maintain control As the British philosopher Thomas Hobbes points out, Governments are needed to prevent anarchy.By providing order over a people, governments are able to protect the liberties of its citizens. Also as the text illustrates, governments are necessary to provide public services. This can be exemplified by the roadways provided for transportation.
