I'd also add that this begs a serious question: who _do_ you trust to own the signal? A multinational corporation? A government? No one? Everyone? Furthermore, how do you rectify disagreements over that trust? I may trust a multinational corporation (especially if I own stock in it and can vote on its directors), but you may trust your government, and our neighbor may not trust anyone. Both of those questions need to be "solved" (if such a thing is even possible), but that's (obviously) a lot easier said than done.
