Answer:
According to the Social Contract of Rousseau, if the government does not fulfill its' role to protect life, liberty, and property, the people can dissolve the government and form a new one. This is because, according to Rousseau, it is the citizens themselves (and not the government) who have sovereignty and therefore the power to determine the destiny of the nation, the government being a mere instrument for this.
Thus, Rousseau adheres to ideas of a libertarian tinge, advocating a limited government and leaving in the citizens a good amount of power destined to control the activity of the government itself.
