What little space we do have allocated to us is constantly under attack, because there's always money to be made from selling RF spectrum. If VHF/UHF becomes just a place for computers sending cryptocurrency to each other, eventually the FCC is going to step in and decide "hey, we could be selling this!" Then it's gone forever, and the age of radio experimentation is over.
If you want to go interfere with licensed transmissions to protest the FCC, go for it! I hope you enjoy the inside of federal courtrooms, though.
