" a perfectly competitive industry is an utter impossibility in the real world. The requirements for this status are numerous and ridiculously otherworldly: completely homogeneous products; an indefinitely large, not to say infinite, number of both buyers (to stave off monopsony)5 and sellers (to preclude monopoly); full and complete information about everything relevant on the part of all market participants; zero profits and equilibrium. The reductio ad absurdum of this objection is that, not only could roads not be privatized under such impossible criteria, but neither could anything else be. That is, this is a recipe for a complete takeover by the government of the entire economy; whether by nationalization (communism) or regulation (fascism), it matters little. "
