Not the same as on an unessential frequency 40 miles into the boondocks.
Your ignorance of radio communication is enlightening. Radio communication is regulated by International law as well as FCC. US frequencies are regulated in conjunction with other countries. It again, is not all about us. There are no unessential frequencies. Your "unessential" freq. may be being used by railroad, aircraft, LE, repeater communications across country, and on and on as well as the same in neighboring countries.
Me using some "unessential frequency" while hunting where I am right now located (in the middle of nowhere) could jam Border Patrol units in the field, CBP repeaters, SO repeaters and simplex as well as radio operations across the border in Mexico. It is not "apples and oranges". As an example LAPD narcs, thinking they were on an unessential frequency while following a perp, jammed my agencies repeater input on one frequency that they could not hear and caused an agency of 400+ officers to shut down one entire frequency. They had no idea they were doing that because they could not hear the output on our frequency.
And as a Ham, if you use those frequencies without a license, other Hams will "fox hunt" you down and report your violations to FCC. They do act on those complaints.
