There's definitely a faction that's concerned first and foremost with markets (hardcore economic conservatives) that you've left out, which historically, especially since 1980 or so, have probably been the most influential "far-right" movement in the United States. The House Freedom Caucus is definitely not a collection of the most socially conservative members of Congress, nor does it concern itself chiefly with social issues.
It occurs to me that, based on your description (which I think is off the mark), I would agree with virtually nothing that the first group espouses, when in fact I am inclined to support them over the second.
I actually think that economic conservatism is highly correlated with the first group (I did note trade, for example).
Yeah, but the true economic right is motivated by very different factors than the Religious Right. These groups are reconciled to a degree that they are not with the nationalist right, but they are not the same thing.
