Ok lets go at it at this angle. If your neighbor came over and asked, CW may I use your rake that you have in the shed to level my yard with, your answer is going to be no I bought that rake 30 years ago to level my own yard and someday I may want to rake again so you can't use it?
Permission in this case= MY verbal permission for you to use the rake. Permission for use of frequencies= a paper LICENSE or written AUTHORIZATION from the controlling agency to occupy frequencies.
If *I* want to allow you to use my rake, I can. If I am P.O'ed at you, I can say NO! You can't. Period and end of story. If NTIA, Army, Navy, USAF or other controlling agency holds frequency assets, it is the same thing. They may hold them "in the barn", so to speak until the cows come home. Like the rake, they ARE the property of said agency until they formally release them OR NTIA reassigns them. If you trespass in my barn or swipe my rake there are penalties. If you trespass on frequencies, there are penalties. There is where the gamble is!
This is where we are at with the freqs, at one time they may have served the military, but with todays technology, and the gear that the military has now be honest do you really see them using 27.575 for anything?

Yama, you are not reading my replies. You are thinking like a CBer!! Now before you think "WOW! He's insulted me," look at it this way. From the standpoint of CB radio, the first thing one is going to think of is AM and SSB and jabber, jabber, jabber, jabber, jabber. Frequencies are not necessarily used JUST for voice operations! The CBer goes up on 27.445 and hears a short "brrrrrrp". "Hmmm, he thinks, just a burst of static". BRRRRRRRRRRUP! "Why, they ain't nobody using this here channel, so I kin just shoot some of that old skip thar".
That "brrrrp" might have been a type of Pactor, Packet, RTTY, or a tone signal that turns on remote bases, or other communications assets. They can be used as digital links to other frequencies similar to the way hams use 440 or 220 to link to a 10 Meter, or a 6 Meter repeater. They can be HF uplinks and downlinks to satellites that only require that short "brrrp" or a quick tone that sounds to the CBer like static or some mysterious noise. That's what they WANT you to think, and they aren't going to tell you, YES, we' re a-usin this here channel!!!!!"
Some are buffers between other frequencies that DO get used for various purposes. And THEY-ARE-NOT-GOING-TO-GIVE-THEM-UP-ANYTIME-SOON!!!
Once again, they do not HAVE to tell you what, why, when, and how they will use their frequencies, and they will use them--or NOT use them--as they see fit.

Now this gets back to the root of the whole thing, if cbers as a whole would petition the fcc for a few more freqs, and the ARRL would stay out of it there is really no reason that a few more freqs could not be given. Because the argument that they belong to so and so kinda falls back to the rack thing, in that if they have no intrest in them why not let them be put to legal use
