The mesh networks target the last mile problem. That is the big point to be addressed as it causes the affordability issues and is the main connectivity bottleneck. To improve the existing system full decentralisation is not necessary.

Exactly. It would allow companies like Google to get involved by leasing out their fiber backbone at cost for long-distance comms.

Right now they're restricted by last mile costs, but otherwise they're incentivized to simply provide the fastest bandwidth to the most people, as their revenue simply scales with internet usage as a whole.
