You mention the use of Tor and TrueCrypt. But, how effective is a lock against the thief who is already in the house? Besides, in my part of the world Internet speed is not like that of US (which I have not experienced) or of S Korea (which I experienced and couldn't believe it was that fast) and neither is it so good in the countries where oppressive regimes are still holding ground (albeit with the (in)direct support of many western powers including the USA) the speed is very slow. Use of sth like Tor reduces it to a mere trickle. Though a in particular case the pain can be endured but when it comes to an entire nation then it's not a solution at all.
