I'm trying to view the recent FCC Net Neutrality reversal in a positive light; will it finally force us to abandon traditional ISPs? Building a mesh seems like the proper solution to ISPs that won't treat our packets with respect. Given the correct cost/performance ratio I think we could see a mass of tiny devices scattered around the neighborhood/town/city/state/country with backhauls in as many places as possible.
If they are cheap enough and self configuring then we could just plug them in to any available electrical outlet and go. Put a couple in your house and put a couple in your parent's/sister's/cousin's house. Talk to your neighbors and have them plug a couple in. Head to the local taco place and have them plug a couple in. It shouldn't be hard to get everyone on board: "Plug this in and get free {libre|beer} Internet access!"
