There are very few things a government should do. That’s because the essence of government is force. And, in a civilized society, force should be kept to a minimum. So the only legitimate function of government is to protect you from force. Which implies an army to protect you from violence from outside of its borders, police to protect you inside of its borders, and a court system to allow you to adjudicate disputes without violence.
But those three functions are actually far too important to be left to the state or the kind of people that inevitably go to work for it. So the only three things that it can legitimately do are the very three things that are too important to trust it with. It’s almost a contradiction of terms. In point of fact, there’s nothing the State does that shouldn’t be left to entrepreneurs and a voluntary market.
