That has certainly been true in the past. The government gave hams - junk frequencies. Hams turned around and figured out how the use them effectively opening the door to commercialization.
I believe in the early days of radio hams we given the junk bands above 1.5Mhz because they were considered useless.
Just give this white space to hamradio operators we will make good use of it.
Hardly. No coders were given full access to everything above 30mhz and yet repeaters remained mostly dead. They begged for HF access, got it and the VHF/UHF bands have gone mostly dead except during contests.
Long ago it may have been true that you give hams useless spectrum and they make use of it but not today.
