It is a simple matter to make voters demand central control of all computing resources. All they have to do is mention the fact that terrorists, drug dealers and child molesters also happen to be computer users. Can't even offer a counter-argument against that without being marked as a pedophile sympathizer.

Put enough fear into the population and they'll accept anything any authority presents as a solution. That's the danger of relying on democracy. You depend on the public to do the right thing and the public is easily manipulated.
