It's mental illness and wishful thinking all wrapped up together. They believe whole heartily that if they don't agree to the rules of society they are under no obligation to follow societies rules unless a rule benefits them then they should also benefit. I'm sure there are some who are just using it to grift but I believe a majority of them honestly have some form of mental disability because I watched the trial for Darrel Brooks who decided to drive through a crowd at a parade killing six people and injuring several others and he was literally dumbfounded that he was found guilty because he believed the law didn't apply to him as a sovcit.
