you've clearly not used any of the modern roaming-enabled encrypted overlay networks that people have been working on. one example is hyperboria. i connect to a handful of public relays (and one that i host myself) and no matter where i am my device is reachable at the same ip address. the address is an ipv6-encoded hash of the public key that is used for routing. its actually really neat, and you don't need to wait more than a few seconds for the routing tables to update if you change locations.
I haven't even heard of these things, and your description sounds like so much effort I'm not even going to be looking this tech up. If it's more than "install using an installer, not a terminal, and then it just works(tm)", it's not the kind of thing that's going to get people who weren't already on board, on board.
well, i didn't say this was a consumer-ready network. i'm just pointing out that the technical issue behind "how do i route to my aunt's network if she changes her location" is a solved problem. nobody is saying this stuff is ready for mass consumption. we are building and using these things so that they can eventually be easy enough to use that we can replace current-internet with future-internet.
