I believe mining companies hold a lease from the crown, much like forestry and other companies or even trappers. I've looked into holding a de jour court. I even attempted once. The challenge was getting people to even agree at that level. I gave up as I knew people were not ready for that. Almost everyone wants to force their view and I made a declaration of peace. So I've been looking for non-violent ways to fix this issue. Holding a de jure court requires a lot of training, awareness and peace. People are just not ready for that yet.
The 'heir of God' as you so beautifully stated, is us. The question is how to stand in that authority and power. That is what I am exploring without the de jure court.
