With respect, I strongly suspect that you misunderstood what happened in your friend's case. Obviously, I don't know the details of it but I can assure you that presenting your birth certificate and a "bill of exchange" that you printed up on your home computer simply won't work. Without going into details, I work in that sort of area and have dealt with sovereign citizens as part of my work and those tactics do not work.I didn't just read the internet, I went into the field and met the sovereigns and went to the courts to find out how things worked out and spoke to the prosecutor and heard the judge.
We all make assumptions and, of course, we all prefer articles or bits of information that suits our worldview. That is why it is so important to question things and research widely.
