Indeed. Which is why all the metaphysical and moral qualms you have with Korihor do not subtract from the fact that he taught free market economics.
Let's take one point at at time and see if we can make some headway here. First, please show me where the Book of Mormon - anywhere - sallies into economic theory or mentions free market economics, or any kind of economics, other than general observations of buying and selling and economic activity among a people.
Korihor taught a form of radical, atomistic individualism and atheistic materialism that is quite hamonious with long lived trends in leftist social and political thought over some two centuries. It is not compatiblie with modern conservatism.
However, there is a strain of what I would term "strong" libertarianism, including libertarian anarchism, with which Korihor might find common cause in some salient matters.
Keep in mind, however, that the radical, atomistic individualism of the late 60s and 70s, including the sexual revolution and other forms of antinomian social radicalism, were, while celebrated by some in the more militantly secularistic wings of the libertarian movement, the creations of the sociopolitical Left.
That, however, goes back well before the sixties, to Shelly, Beauvoir, Sanger, Kinsey, and other notable figures among the early Left.
The simultaneous and seemingly schizophrenic focus of the modern Left upon, on one hand and in certain venues, intense, atomistic personal autonomy, and collectivist regimentation and social control on the other, in other venues, has been noted by other thinkers, and I'll just note it again here.
