The Nyquist rate (and Shannon's theorem even further) severely bounds digital communications bandwidth in the little bit of usable bandwidth that lies below 100 MHz. The long distance and irregularity of the propagation puts additional bounds on the number of simultaneous transmitters. So there are good reasons other than just censorship and rent-seeking to desire the short-ranges available in the shorter bands, such as the increase in simultaneous talkers (if you don't propagate as far, someone closer by can share the frequency), and the additional bandwidth available.
That said, the 20 m band is plenty fun, even if every idiot in the world can't use it.
