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!
