What about government commercial negotiation information, surely the government can (should!) keep that secret at least until the negotiations are over, otherwise every single purchase made will have them ripped off due to information asymmetry.
Troop locations are another one. If you know exactly where everything is it gives you a huge advantage, and to a lesser extent where they've been.
Surely there are some secrets we can acknowledge the government can keep, for a time. The problem only arises when the executive branch abuse the classification system and label embarassing, non-sensitive (to the country, maybe not to their reelection) information as sensitive information.
In all honesty, I am an Open Government proponent, which means that I think the justice and pressure of having the entire society able to monitor the situation will self-heal any attempts at exploitation. It is only because you don't know how much the Government pays for things, that it is able to put you into debt so it can pay for the things it 'thinks it wants'.
Turn the light on the whole thing; make all procurement open to the public, simply put a 24/7 webcam on anyone who is functioning in a government role, and let it work. Open communication is the only thing that has truly propelled the species forward .. and yes I acknowledge it is 'a radical position' with fatal flaws, but alas ones viewpoint doesn't always have to be .. Right .. now, when discussing the nature of our abundant universe..
