This is one place where I agree with you about the benefits of writing down a model.

We can have much more civilized, and possibly even fruitful discussions, if they have to relate back to features of the model: i.e. "that elasticity should be 10% lower" or "there's a missing feedback loop that should go here."

Eh, he seems pretty reasonable all things considered.  Where I'd push back is that it's rather hubristic to think that we have the ability to calculate the efficient quantity of carbon production; much less there even being a single correct answer when likely the costs, benefits, and beliefs are totally heterogeneous.
