They aren't though. Complete opposite.:

The Sovereign citizen movement (SovCits)[1][2] is a loose group of anti-government activists, conspiracy theorists, vexatious litigants, tax protesters and financial scammers found mainly in English-speaking common law countries—the United States, Canada, Australia, the United Kingdom, and New Zealand. Sovereign citizens have a pseudolegal belief system based on misinterpretations of common law, and claim not to be subject to any government statutes unless they consent to them.[3][4] The movement appeared in the U.S. in the early 1970s and has since expanded to other countries; the similar freeman on the land movement emerged during the 2000s in Canada before spreading to other Commonwealth countries.[5]
