Privacy should exist everywhere but there should be a balance. A way to follow the money trail must exist to prevent institutional corruption. For this reason we cannot have secrecy in financial transactions.
I don't consent, though. If you are from the U.S., do you really believe in that document that says governments "[derive] their just Powers from the Consent of the Governed"? Because I don't consent to this.
But I want to know if a politician or police officer is being bribed because democracy depends on it. A free society depends on transparency.
I have no wish to participate in your democracy. I have no problem with you imposing whatever requirements for participation that you wish. I have no desire to be a politician or to be ruled by one, and I have no interest in having my financial freedom infringed simply to prop up your failed idea (democracy).
