Have you ever heard of “outernet” ?
Stuff like this will force expansion of outernet.
The problem with the concept of the “outernet” is that it still requires use of core infrastructure on the Internet!
Understand that the Internet is not this autonomous nebula of interconnected devices. There are a small number of high-level global root servers that act as the authority for all domain name services across the globe. If you think you can fire up this “outernet” and browse to FreeRepublic.com, you’ll only get to it by routing through an Internet DNS provider to FR, assuming FR is still online.
In order for an “outernet” to actually work, you would have to have participants agree to use only “outernet-based” endpoints with “outernet-based” infrastructure. That means setting up a standalone network in parallel to the current Internet infrastructure and allowing it to work without outside interference.
I’m not saying it’s impossible, but a truly global or even regional effort to make it happen would require an enormous amount of heavy lifting including infrastructure engineers, network engineers, systems architects, and security professionals all working in concert to ensure the experience is functional, redundant, useful, and safe.
The problem with government interference is that most people will tolerate it. It’ll be “Oh, I never went to that site, so it doesn’t affect me.” By the time the government has pruned your access down to nothing but the sites and endpoints they can track, you’re left with a smoldering husk of what used to be called the Internet, and you’ll probably be hard-pressed to find those engineers (alive or otherwise) since most of them are either working for the government or dead because they refused to assimilate.
Certainly in relative densely populated areas a local parallel network could be assembled using largely existing infrastructure.
