Monopoly rights to spectrum should have ended once cellular modulation schemes went digital. The modulation techniques used in 3G/4G/5G systems are already agile enough that they really wouldn't have a problem with all the carriers sharing all the spectrum all the time. Carriers and other license-holders would have to do a token amount of coordination among themselves, probably similar to the settlement-free peering arrangements that the tier 1 Internet networks use. In return, we would all get more efficient real-time spectrum allocation, and carriers could instead spend their billions differentiating themselves with infrastructure and capacity improvements rather than locking out anyone who didn't spend billions on spectrum 10-20 years ago.
