Dang.
All I can suggest is Stick to the Book.
Have little stickies poking out the top, stuck to major trouble areas like AoO's, grapples, jumping distance calculations, etc...
When he starts launching into a big spiel, roll the dice FOR him if need be. Then tell him the result. If he starts complaining, open the PHB to the relevant section (hence the stickies) and show him the rules. If it's not in the book, it doesn't fly. Maybe HE knows how to make a knot that would work, but his character obviously messed it up somehow. That's what skill ranks and die rolling MEAN.
If you can get him to accept the ascendency of rules over reality, in this limited setting, you'll have won a significant battle. And sticking to the book, I think, might help. For one, it'll eventually make him realize that he CAN exert power over this phenomenon...and that's what all this over-defining is all about. It's a power play. It's him making sure he's in complete control of his environment. If he knows you Stick to the Book, then he'll go buy the Book, so he can out-Stick you.
Of course, that might only change the nature of the problem...but at least then his arguments will become -predictable-.
