Those folks don't really have an impact on the rest of us. If you believe this nonsense, don't call me for representation. How can a civil lawyer negotiate on your behalf or represent you in court when laws don't apply to you?
Moreover, any legal theory that bears no connection to the laws of this country cannot be used by lawyers without the possibility of court sanctions or bar complaints. In other words, you are cannot be represented by an ethical lawyer. So, good luck in presenting your sovereign citizen theories during negotiations and in court.
