I like my government republican too, and I'm not going to have you twist the meaning of that word. Russ Roberts is concerned about secrecy at the Fed, calling it "unacceptable in a democracy", titling the post "A Republic, if you can keep it". I guarantee you the founders didn't feel obligated to announce they were going to celebrate Christmas with a bunch of Hessians.
Some policies require secrecy to work well. In our republic, we constitute a limited government, and empower it to make policy consistent with those limits as long as the means of making it are necessary and proper. Secrecy, in many cases, is both necessary and proper. Certainly in a financial crisis it is.
I plan on keeping my republic, Russ. That does not entail mutating it beyond recognition into some libertarian construct.
