That does make sense. I think I agree.
However, there's a lot more to an inner tube than resisting sharp things. Think about the durability when fitting/removing and ability to resist pinch punctures and debris inside the rim.
I also believe that the heavy duty tubes are less likely to shred themselves up if you get a big puncture and are riding flat on it.
