Well you totally missed the point.

There's plenty of substance with Lessig. I just am talking about one bit of substance, which is whether he has the pragmatism needed to get and then to do the job or not.

The glasses (which I actually like; not sure where you got your "fact"... but I doubt US voters will) are the form here, to use your word. Not the substance. They are trivial.

So yes, the glasses are not substance. His lack of pragmatism in clinging to them is substance.
