I think at some point, this will be impractical and you will have to either commit digital suicide, or accept it. This is really sad, but I see it as inevitable. Governments will always have the power to pull this stuff off without our consent. If they can't get these things their way, then they will (or maybe already have) localized EMP charges that can disable targets. With the police force that is becoming increasingly militarized, I can see a car chase ending differently in the future. I don't support it, and yes we should do something about it. But what? Do the people really need to wait until it's at the brink?
