Molinari opines that the reason people resist a free market in security is that they believe that society is essentially artificial rather than natural. Thus they think that it is necessary to have legislation and authority to modify, remake, and mold society. This authority either takes the form of rulers and kings, or the form of Rousseau's mythical general will of the nation. According to Molinari, this belief in the general will is the essence of communism.
If there is no unanimity, if there is still dissension after the debate, the majority is in the right, since it comprises the larger number of reasonable individuals. (These individuals are, of course, assumed to be equal, otherwise the whole structure collapses.) Consequently, they insist that the decisions of the majority must become law, and that the minority is obliged to submit to it, even if it is contrary to its most deeply rooted convictions and injures its most precious interests.
Molinari answers 'no' of course, and concludes that "the moral foundation of authority is neither as solid nor as wide, under a regime of monopoly or of communism, as it could be under a regime of liberty." Finally, Molinari gives some advantages to competing protection agencies, and how it might function.
That is the theory; but, in practice, does the authority of the decision of the majority really have this irresistible, absolute character as assumed? - Gustave de Molinari, The Production of Security
Under the rule of free competition, war between the producers of security entirely loses its justification. Why would they make war? To conquer consumers? But the consumers would not allow themselves to be conquered. They would be careful not to allow themselves to be protected by men who would unscrupulously attack the persons and property of their rivals. If some audacious conqueror tried to become dictator, they would immediately call to their aid all the free consumers menaced by this aggression, and they would treat him as he deserved. Just as war is the natural consequence of monopoly, peace us the natural consequence of liberty.
