> i.e., sparks the kind of innovation needed to break the ISP monopoly
How so? Internet is infrastructure, LTE is infrastructure (from the same ISPs) - mesh networks don't scale due to inefficient wifi and too little spectrum. You can't break physics.
The innovation you have is paying for a VPN and pay up for your non-ISP-netflix traffic.
What do you think would be possible? If it's over the air it will be regulated and licenced (i.e. non public spectrum) and if it's not over the air you have huge costs nobody is willing to pay to build a network (even Google ditched Fiber due to costs?)
