Haven't watched the video yet, but have been researching this topic.

As I understand it, it is necessary to establish a clear chain of title and file a land patent. Not sure how one goes about removing ones self from the tax rolls. I seem to remember that part of the sales contract is agreeing to assume the payment of taxes. Not sure how one would go about getting out of that contract. I did cancel my voters registration a few years ago to remove that nexus.
