Two Near-Universally Accepted (but Incompatible) Propositions

Quote from Hans Hoppe:

First off, among economists and philosophers two near-universally accepted propositions exist.

First: Every "monopoly" is "bad" from the viewpoint of consumers. Monopoly is here understood in its classic meaning as an exclusive privilege granted to a single producer of a commodity or service, or as the absence of "free entry" into a particular line of production. Only one agency, A, may produce a given good or service, X. Such a monopoly is "bad" for consumers, because, shielded from potential new entrants into a given area of production, the price of the product will be higher and its quality lower than otherwise, under free competition.

Second: The production of law and order, i.e., of security, is the primary function of the state (as just defined). Security is here understood in the wide sense adopted in the American Declaration of Independence: as the protection of life, property, and the pursuit of happiness from domestic violence (crime) as well as external (foreign) aggression (war).

Both propositions are apparently incompatible with each other. This has rarely caused concern among philosophers and economists, however, and in so far as it has, the typical reaction has been one of taking exception to the first proposition rather than the second. Yet there exist fundamental theoretical reasons (and mountains of empirical evidence) that it is indeed the second proposition that is in error.
