I think GP is saying that there would be a sea change IFF 1. there was legal unlicensed radio bandwidth for any radio services that had cognitive radio capabilities (constant frequency hopping, coordinating frequencies with other nodes after negotiating what frequencies, ensuring the radio bandwidth used is only using whitespace or can be empirically proven to not interfere with other radio transmissions) 2. HAM radio bands aren't touched. Some HAMers are grumpy enough about radio licensing dogma / vigilante radio spectrum law enforcement duty, no need to kick the hornets nest of telling them that not only are radio licensing rules changing from the paradigm introduced in the 30s (see point 1) but that it would remove some of their own dwindling radio bands as well.
