My previous post, specifically the blue-sky solution, was injected with a dose of sarcasm.
Any prescribed solution to a problem involving interpersonal dynamics (and 4GW is inherently about the people, not the machinery of the State), especially in the absence of reliable examples, can only be conjecture. The real world is complex.
The city-state or resilient community solution to the problem of 4GW is a scenario of mutually-assured destruction for the State and opposing 4GW force. Remove a person's dependence for security/safety on the State and you erode their loyalty. If a 4GW force no longer has a State to damage, then their base of support is eroded as well (the Plausible Promise no longer exists).
Currently the infrastructure required to support a massively distributed and resilient society can only be deployed by the State; the cost is just too great.
Where we see the sort of resiliency that protects against a significant 4GW threat is in the corporate world. Large companies have the resources to disperse their offices, infrastructure and staff through multiple regions, and spend enormous amounts of money protecting them (through data/physical security measures as well as healthcare plans etc).
My current blue-sky theory is that the best fighters of 4GW will be the mega-corporations.
States are tied to specific geographic regions, cultures and ethnicities; corporations are not. State legislature is grinding slow at the best of times, and having a faster decision-making loop than your opponent is critical in 4GW. Corporations have massive advertising budgets and are already adept at molding public perception, another key component of 4GW.
We already identify with brands of electronics devices, connect with obscure automobile manufacturing groups across the internet and spend hundreds of hours watching brand-positioning advertisements. Does the future State have a Sony logo?
