Yeah, there are a lot of projects out there to make something like this. I've been looking into it for over a decade and have ran a node from time to time to check things out but it is just not robust enough yet. TOR was an attempt to make it so you could get to the larger world even if you are in the "dark web" but its not really a great setup. I am thinking something that has no interest in being a part of the "larger web" even if it exists on its infrastructure with a large amount of mesh systems interconnecting it where needed as a backup in the event it somehow can be profiled and "banned" from the larger infrastructure or so people that don't give a fuck about paying for an ISP can connect to it anyway.
