Challenge: Name one federal government agency that US citizens need. It must be one that is essential and one that cannot be replaced cheaper and better in private sector.
Go!
It is a fraud in fact when the original Nationalists usurped the voluntary nature of the original Federation of Independent States (1775 to 1789), as documented in so many historical records. There are no "Federal" agencies, not since 1789, not unless it is agreed upon that the Common Law is a Federal Agency.
If people can agree that the Common Law was a Federal Agency since 1775, and as such the Common Law was, and still is, The Law of the Land in America (A Federation of Independent States), then people can agree to use the Common Law to discover, indict (presentment), and try every single treasonous criminal currently abusing the National System of Legal Plunder set up on 1789.
So...a true Federal (voluntary association) Agency is the Common Law, but it only works if people agree to use it as such. If people agree to follow the dictates enforced by false Federal Agencies (National Agencies), then people get what they pay for in fact.
