What do sovereign citizen extremists commonly believe regarding the government's authority?

Sovereign citizen extremists commonly believe that the government has no authority over individuals. This belief stems from their ideology that individuals can declare themselves as independent of governmental regulations and statutes, asserting that they are not subject to the laws imposed by the government. They often think that the U.S. government, and other legal systems, operate under a form of illegitimacy, making them feel exempt from legal accountability. This mindset leads them to reject traditional legal principles and to pursue various forms of legal challenges based on their beliefs, which can manifest in encounters with law enforcement and in legal proceedings.
