Fixing/replacing the physical (atoms) is harder than the digital (bits), but it's possible. The dream is something like HAM radio level autonomy/sovereignty, but most of our high bandwidth wireless tech that operates over long distances requires line of sight.

So if physical wires/optics are the problem, we'll need to incentivize high density citizen run wireless mesh, or have a tech breakthrough that makes things like roll-your-own cell towers affordable to you and me.
