This is a common behavior among many libertarians/ancaps (although still a minority). They tend to believe that they can live outside the law. And it's sad, because they usually don't harm anybody with their little misdemeanors. It usually looks more like a child reveling against their parent's arbitrary laws, than a crime for which they should go to jail or even prison.

Adam Kokesh would be a very good example. [1] [2]
