I have written where I disagreed with Brother Bahnsen on politics, but, there is actually one thing he said that I do agree with on politics. "All civil governments must refrain from coercion in areas where Scripture has not prescribed their intervention."
As part of general equity the Government is to refrain from using State power in areas where people are not outside of God's Moral Law. This leaves us with a society that is free, but, virtuous. God Given Rights are to be kept from being trampled on and we are to be free within the framework of God's Law.
For example; property rights and freedom of exchange. The right to self defense. Et cetera.
