IMO the biggest problem with markets is externalities, many of which are actually planned and regulated IN by special interests. Getting the externalities out is no trivial technical matter. “There’s no such thing as a free market” might be more universally true than there’s no such thing as a free lunch, so any reliance on free markets to solve socioeconomic ills is extremely naive, speculative, disingenuous, or at the very least technologically premature. I agree that the “one drop” theory (that the existence of even one non-defense government program constitutes socialism) is libertarian/tea-party nonsense. All real (in vivio & in situ) socioeconomic systems are hybrids if viewed through any legitimate taxonomic lens. Taxonomies drawn from empirical observation can be useful in socioeconomic systems analysis, but categorical generalizations drawn from theory, philosophy, or ideology (and the countless false dichotomies that follow) are generally the bailiwick of scoundrels and fools.
