Limited government is important because limiting government preserves individual liberties and protects certain rights and freedoms. It also protects private property and enables citizens to have more control over their own lives.
Not limiting government enables the government to have absolute power over the citizens. In an unlimited government, the government makes decisions on behalf of the citizens, resulting in the loss of individual liberties. Both the United States Constitution and the Bill of Rights were designed to limit government. A limited government has legal limits on its power and can only pass laws that do not affect personal liberties.
A limited government prevents the government from employing extensive control over people's lives, freedom of speech and actions. It also prevents the government from interfering with the implementation of civil liberties. Moreover, it gives citizens the opportunity to participate in political and social issues and local government. In addition, it provides a free market economic system that enables citizens to have financial freedom.
Limiting government increases individual freedom, however, limiting the power of government can also limit the government's ability to take action on behalf of its citizens. For instance, if the government is too weak because of constitutional limitations, there is a potential risk of citizens having their freedom violated by non-governmental concentrations of power.
