I've just recently watched Die Hard 4.0 (also known in America as "Live Free or Die Hard") and I wonder what would happen if anyone actually managed to pull off such a "Fire Sale" internet take-over event. In all probability, in my mind, there would be anarchy for a while ... and then not. As these sad little kings sit on their sad little stolen electronic hill, a good proportion of the population would adapt, abandon electronic infrastructure and go back to semi-rural lifestyles. Let the tiny dictators have their irrelevant kingdom. The rest of us will be over here growing crops, trading handcrafts and ignoring you. Yes, life will be harder that way than it is today, but it would be harder still to cling to a digital lifestyle if it were run by an evil dictator. And if there's one thing humanity is good at, it's the path of least resistence.

PS - Of course, for many people, the path of least resistence will be to kill and eat their neighbours.
PPS - So let's not try any of this today. Or tomorrow.
