> Taken a step further, the primary relationship of a government to its people is the threat of violence for not following the laws.

This is true in pretty much the same sense that it is true that the primary relationship of a people to its government is the threat of violence by the former against the latter for failure to deliver on demands. (The extent to which either is actually truly the primary relationship in practice is pretty much precisely the extent to which the government has lost legitimacy.)

> Free market thinkers challenge the assumption that government should be granted a monopoly on force but rather there should be competition in all areas of society.

The government is simply whatever entity (including a collection of entities) in practice holds a monopoly on the legitimate use of force. You can question what the nature, scope, composition, and role of government should be, but questioning whether it should have a monopoly on the legitimate use of force is exactly like questioning the assumption that a triangle should be a three-sided polygon.
