The sovereign citizen stance is accurately characterized by the term "gobbledegook." It is predicated on the false legal theory that the US federal government has no legal authority on citizens that claim they are only beholden to individual states. This viewpoint is based on the original Articles of Confederation, while ignoring or disregarding the authority of the Constitution. It also employs fictions such as the assertion that courts that have gold-fringed flags are courts of Admiralty and therefore are illegitimate. There are some opinions that should rightfully be disregarded. Edit: this is also covered by the OP's links.
