Totally agree,
I maintain two existences, one with electricity and one without!
Second to seeds as currency is land. Especially if it's distant from government's notice
It is possible and practical for governments to control/shut-down the Internet even if the electric is still on. With relative ease most governments can deny a region access to communications. Beyond that is the simple manipulation of packets. If the FBI can turn Tor into a tool to their advantage the Internet in general is a piece of cake.
