The author's misuse is all the more painful for being an econ grad student at my alma mater, GMU. A former professor of mine, Russ Roberts (the man behind the Hayek vs. Keynes Rap video), even used a similar example ("Does Ford have a monopoly over the Taurus? Cars? Means of transportation?") to show how little objective utility the term “monopoly” holds. The more narrowly one defines the market, the more one is likely to “discover” monopolies.
