Well said, I'm on board with all of that and I don't see biblical libertarianism conflicting with that at all. Self-government is the foundation of family, church, and civil government. All 4 spheres are separate, but subject to Christ. You described the appeals court process instituted by Moses, the foundation of which was individual families that were supposed to be made up of self-governed individuals.

The state must not swallow up that which belongs to the church, family, or individual. Nor can the church wield the sword against evildoers. The radically minimal biblical system of government recognizes the equal ultimacy of the one and the many, rooted in the Triune nature of God. No man is an island since our behavior is consequential to others, but each individual will give an account of himself to God.
