There are finite amounts of everything. Free market economics solve this problem all the time. There are finite amounts of food, land, energy, shelter, human resources, etc. The problem isn't that spectrum is finite, it's that there is no way to prevent interference. It's questionable if the FCC is really optimal though. There are huge amounts of spectrum still devoted to dying industries like AM/FM radio and broadcast television.
