It's a technical/commercial necessity to have exclusive use over the spectrum in a given area. If you don't believe me why doesn't every city in the world have a paid wifi network? With 5Ghz it should be faster than typical 4G/5G speeds, and it only needs lampost level APs, pretty similar to the microcells that carriers deploy but an order of magnitude cheaper. Instead mobile carriers would rather buy 3 or 6ghz spectrum that only ever gets used in cities anyway, why not wifi in the cities?
ISM is tragedy of the commons; make it free, let anyone do anything and it becomes junk. Carriers need something they have exclusive use of.
