I must be denser than usual today. Because I read it twice but I can't see exactly what it hopes to accomplish.
You still need a ramp onto the internet - which means putting a government or corporate Telco or ISP somewhere in the loop.
And basing things on 'bandwidth given back' or 'processing power spent' is blatantly favoring those who can afford high capacity hi-speed connections and powerful PCs over those less well-heeled. So it's unavoidably economic-elitist at its core.
As far as privacy goes, being 'as private as Tor' is no longer saying much. Especially now that the NSA has wormed itself down to the hardware level. Seriously, who can ever really know what a CPU, GPU, NIC, router, switch, etc. etc. etc.
is reporting back these days? If weasel code is burned into proprietary silicone, it's safely out of sight for all practical purposes. Just tell the chip to do certain things but not report or log it; or, ignore 'seeing' specific things (like an NSA header) in a data packet and Bob's yer uncle!
Talk about FNORD!
No...it's a nice idea. But as long as you're running on somebody else's physical backbone and closed hardware it'll never
be your own private internet. This is a rearguard or short-term strategy at best.
Where we are today is the result of a people problem, not a tech problem.
And it always will be.
