Well, there's two issues here.
First, that it's not a simple matter of how arcane a topic it is it's about how historians construct their subject matter. Salt is a distinct variety of material resource, the existence of which cannot be brought into question, and there's an established tradition of writing histories from that premise. What you're asking for is not only a book on a particular subject, but a book by an historian who has chosen to construct his subject in a particular way, to trace the same historical threads as you are doing. It's a more complex premise, and there's no guarantee that such a thing exists, or at least not in the particular form you're asking for.
Secondly, it also depends on the kind of history that CFCers are into. You're asking for a particular sort of intellectual history that is both elite and provincial, and I can't think of any users with a particular background in that area. Plotinus can give you a lot of intellectual history particularly as regards Christianity, but colonial America is a bit outside of his stamping grounds. Dachs could probably give you something about popular attitudes in the American Revolution, but intellectual histories don't seem to be his thing. There's probably somebody who can suggest something, but they might not be a regular WHer, so it might take time for them to see it.
. I suspect he isn't asking for refutations in good faith, so you'll be wasting your time.
