The proper role of government is to protect our lives, liberty and property against those who would use force or fraud against us. The powers of government should be limited to those same powers that each individual is morally justified in using. We are individually morally justified in defending our lives, liberty and property against those who would use force or fraud to take those things away from us. If it is morally wrong for an individual to do something, that same thing does not somehow become moral because a majority of the people want to do it. If it is morally wrong for an individual to use force to take justly obtained property from another person, then it is not made moral by by being done by a majority.
In order to have a civil society, one that is ruled by laws that apply equally to all instead of one that is ruled by force, it is proper for people to cooperate socially to form governments. It is a good thing to have a justice system to resolve disputes between people. Humans have emotions and biases that often prevent them from solving their own disputes. If you didn’t know whether or not you might be on the wrong side of the law, wouldn’t you want the dispute to be decided by an independent, impartial judge and/or jury? That is a proper role for our government.
Otherwise, our government should let honest and peaceful people do pretty much anything as long as they don’t use force or fraud against others, and don’t infringe on the same right of others.
