There's a lot more bandwidth coming into my house in optical fibre than there is in TV and radio aerials.
a quick wet finger back of envelope calculations suggest that a reasonable radio signal has 60dB signal to noise, which equates to 10 bits deep more or less. and with a total RF bandwidth from 80Mhz to
800Mhz that's about 7.2 megabits per second total raw data rate...and the Internet whilst it supports broadcasting has never really used it - your local link only need take what you are actually watching...
I think the way comms will in fact go, is towards ever more localised RF WiFi style connection to mobile devices supported by a multi terabit optical network replacing all cables.
As to how it gets paid for - well you purchase a wifi 'key' that allows you to use public wifi networks as you traverse them. Like the current licence except the money goes to the network, not to the content providers
