There's always that lawsuit to use as precedent, when some guy got in a car accident in the parking lot of one of the banks and tried to sue the government. The government then said, can't sue us because it's not ours.
C`mon guys really, do you think it matters if its privately owned or national? It doesnt, the mere existence of a central bank is the source of all economic problems. Furthermore if it were public it would be even more susceptible to corruption than now is.
See a private central bank only runs a global ponzi scheme. A national central bank would run the global ponzi scheme + the bureocrats would steal everything, so its much better if its private, atleast they can run their nice global debt ponzi scheme efficiently, isn't that lovely
