I have always been an advocate for more, open, spectrum, and simple laws to outlaw intentional interference. We are not operating dumb radios - we can dynamically change or allocate spectrum channels to load balance congestion and avoid making it worse.
To legally cordon off everyone into separate silos is a hatchet solution to a nuanced problem with much better solutions if you could just incentivize good behavior and punish bad in commons.
I do not believe for a second we cannot technologically transfer h265 video via radio to every individual in even the highest population densities if we had full access to building infrastructure around all of the spectrum of light we use for communications.
