I would not be a fan of having a country Solely based on the ten commandments. I know how little of them I can actually keep. That's the purpose of them, to let us know we have absolutely no chance in meeting God's standards by our selves. Moses laws (not the Ten Commandments), were put in place to allow us to redeem our selves to God by Sacrifice. Jesus fulfilled those laws pertaining redemption when he died on the cross.
A county with the laws coming from the grace understood by Christ's sacrifice would be amazing.
