I agree with your basic premise but anybody who holds any public office should not be granted full rights, leaders need to be forced to give up most of their privacy rights including the ability to invoke the 5th. We need to be sure that they are not lying to us (even state sponsored lies, as a single lie from the government voids any notion of “democracy”) that they are not able to be blackmailed/easily coerced, and that they are accountable for their actions.
