I find myself agreeing with them a lot of times, although I believe a christian couldn't go any further than defending a minarchy, which they despise as just 'less statism'.
But I do agree that most regulations to the opposite of what they're supposed to.
On the theological spectrum, however, I've seen articles defending that calvinism was a good starting point to have a good economy (because of work ethics and such) and defending medieval scholastic positions (on their brazilian website, they claim that austrian economics was born in Austria, a catholic country, because the scholastic tradition in this country was focused on the consumers, not the producers).
