And indeed - as I've said before - I'm not trying to teach economics - certainly not in the way I'd try to teach climatology. Picking holes in other people's proposals is far easier than trying to construct a theory of your own; picking holes is what I'm trying to do with "the Left's" economics.
After this, I wrote some words trying to pick apart the ways in which CIP has misunderstood what I wrote, but I fear it is all too much effort, and I gave up; the knot is too tight. I'm reminded of Engine Summer by John Crowley; wiki has a charming summary; you should read it, if you haven't already.
Since it strays into politics, I'll comment on CIP's idea that Ricardo's comparative advantage can be traced back to Plato, in the sense that "if each person does what he does best, more stuff will be produced". I think that's a misreading. Plato (in the Republic) was keen on the idea that people do what they are "best fitted for", but only because he wanted a stable society, with no possibility of the oiks at the bottom troubling the right to rule of the philosophers at the top. This is the complete opposite of the idea that people should be free to choose their own metier.
