I wouldn't trust them even after all the agencies are dismantled. New agencies get made and who knows what they'll turn into?

The only thing that would work is some kind of widespread ban on the use of gag orders, non-disclosure agreements, and similar legal devices by our government. And for what, so we can trust our own corporations to at least say what is in their own best interest? So then you also have to ban the use of funds to keep them silent. Really, the whole thing is a mess.
