I'm from the camp that thinks if you're trying to make a case (about any subject), you should start with your strongest point and work to your weakest point. Every argument I've ever seen against code comments starts off with the weakest imaginable points. Usually the first point made is sample code like "x = x + 1" with the absurdly unnecessary comment "add 1 to x" - as if that's ever something that pro-comment programmers do. This video at least started off with a novel weak point (somebody using a comment with a magic number instead of making it a constant) although it's just as weak as the "x = x + 1" argument.
