Now, that is true. A land patent [some states grant] can not be encroached upon. Notice the Grant comes forth from within a parent trust. I mean a King did issue forth that Grant, yes? King, as Trustee for his estate in Trust.
Try as you might you will not escape 1st Sam 8. If you are talking Grant, Trust, estate, then you are talking Property. If you are talking Property, you are not talking about matter or thought, you are talking Right of Use.
