The current system isn't perfect, but it's more empowering to the common person than incentivizing anyone who has access to any information to sell it to the highest bidder, or to make unilateral decisions that affect everyone in society. At least I get to vote for someone I trust to make the right decisions.
There are plenty of people, especially in red states, who have complete faith in elected and appointed officials to decide what information should be public and what should be private. The personal beliefs of any given government employee aren't any more valid than anyone else's. I don't want to live in a society where any one person gets to decide what's in the public good and what isn't.
If you think the system should be changed so that anyone who has access to classified information can make it public on a whim, then vote for people who will implement that as policy. I don't agree with that idea, but it's a valid political belief and it's at least worthy of debate. But it isn't up to me, you or any other individual to make the final decision. Everyone should get a vote.
