Who bothers to check call-signs to see if they are valid or if the operator is within their license?
Mine expired years ago but I key up with it anyway. Nobody else knows the difference. If I want to operate on other bands, I'll just drop the appropriate letter.
Hams using the guns of government to impose their will is no different than calling the cops on your noisy neighbor, or broadcasters calling the FCC on pirates.
The FCC is preventing the free market from establishing a sort of title to those repeater channels, and requiring the use of the FCC to persue trespassers. And, everyone involved is subject to arbitrary ineffective authority.
In L.A., local broadcasters coordinate STL frequencies amongst ourselves before we seek FCC approval.
Hams believe in the fantasy that a piece of paper make something right or wrong, and that some people with badges have authority. They are part of the problem because they support the veil of legitimacy.
