I hope that in this light we can agree that using the term "free market" as a cudgel is a sign of immaturity.

I think you're caught up in an is/ought conundrum though: "idolizing the idea of a completely unregulated market" is the discourse! That's the pro-side rhetoric in a nutshell, how bills and laws get passed, and how the (US) economic system is constructed. So don't blame my inference, it's just what I'm reading in the newspaper.
