Larry Moss says that spectrum rent is entirely artificial, because technology could make almost unlimited amounts of spectrum available. Larry forgets that this spectrum-expanding technology is expensive. In effect, it substitutes capital for land. Here's an analogy. Imagine a third-world town of scattered mud-brick huts. Larry would argue that land is not scarce, because the town's entire population could fit into a single New York City highrise! Spectrum actually helps clarify Georgist concepts. Title to spectrum is just the publicly-created and policed right to broadcast at a certain frequency and power in a certain location. In effect, it is a circle of land centered on the broadcast tower, with radius determined by power. Clearly this title has a completely separate value from the value of the equipment, or the studio that produces the broadcasts. Landowners can't easily move structures from one site to another. But broadcasters can move signals from one frequency to another by turning a dial! Polly Cleveland
