A hidden state that sets its own agenda and has its own politics defined by its own economic and power structure is definitely a bug. Because who controls that state? Usually it's run by the people for their own personal goals which usually includes profit and power, i.e. the CIA being a great example of a system that was growing in that direction but was impeded over time. Do you want tyranny like that having an undue influence on the government?
