There is none, anon. You were born at the wrong or time. The best you can hope for is that Antarctica melts enough and becomes a new frontier, space opens up in a big way, future drone warfare repopulate regions but leaves capital intact (and the land is given out like candy to resettlers).
Otherwise there's no going back without collapse. Everywhere is going to be connected. Just like people needed the water of th er Nile, and had to endure the iron fisted autocracies of Ancient Egypt, so too will you be dependent upon complex civilisation and forced in a myriad ways to play the game or be destroyed.
