But your interpretation of the Bible is not obvious to anyone besides niche circles of you and your ideological friends. Even the Catholic Social Teaching enjoy more power. Not soldiers, but money, priests and journalists.
You think that your interpretation of the Bible is "true", but to people outside of your circles it's a claim identical to claims of any religious or secular ideology. You are no different to outsiders, exept you have less power than many other interpretations. Your belief in your interpretation of the nature of God gives you exactly 0 additional power to rule effectively.
It's possible that secular libertarians are richer and could hire more journalists than christian libertarians (though both are VERY niche), and yet you criticise their ideology as less feasible than your ideology. Only because you feel that your ideology is more "true". Kind of irrelevant to outsiders when it gives no results.
Look, I would love a more libertarian system, but I'm pretty sure, from looking at the world and evidence, that your religion is not an useful tool for this goal (if any is possible - human nature tends to make art of politics statist and highly pro-regulation, as I mentioned before in this thread).
So, as a tool, not useful. As a "truth", my apologies, but I honestly think that you are mistaken and that Christianity is not true.
