The radio spectrum is for everyone but needs to be regulated to minimize interference. Some talk about spread spectrum allowing everyone to share, but that requires regulations about the spread spectrum protocol and not jamming frequency with music.

The government divides up the spectrum for government, commercial, amateur, and public use. Amateur is not public use since it limits what can be done with it, like not playing music. It is more like public university. Ham radio has stagnated because it mostly uses analog or old digital modes for chatting and making contacts.

The VHF/UHF amateur bands wouldn't be that useful. They are too small for mobile data or Wifi. For unlicensed use, the power would have to low to prevent interference because they go to the horizon. It could be used the same as 433MHz and 900MHz but I don't think that those are overloaded like 2.4GHz. For commercial use, they could be turned into business walkie-talkies; I don't know if there is demand for those but would be pretty low value usage.

The one thing that they might be useful for is digital FRS, there is need for more public walkie-talkie frequencies. But that would have to be highly regulated in terms of protocol. And could turn into CB radio, making it useless for regular communication unless there are rules about jamming with music.
