Ho Kay..
Lets take a break from the physics debate for a bit and get back to the original question, which was: "Why can't you use auto brake MAX for landing" or something like that.
All other parameters being met, auto brake lo and med engage upon main wheel weight on wheels. MAX engages when all of those parameters are met PLUS NOSE GEAR weight on wheels.
So you are the greatest Pilot in the world, you decide to do a snappy arrival, you select auto brake MAX. You touch down flawlessly, noone feels the mains touch down, the SMOOTHEST landing(s) in recorded history. You demonstrate your superior airmanship by stretching aerodynamic braking until you can no longer hold the nose off..
TOUCHDOWN! The brakes apply FULLY, the Grandmother in 39C loses her teeth to the back of the head of the unfortunate sot in 29C, you actually make the taxiway behind you and every other unsecured item in the airplane is now embedded in the cockpit door like something out of "Carrie".
Thank God for that armor plated door!
So the question should not be: "Can you use auto brake MAX?", but "Should you...?"
Naturally, if you are someone who routinely plants the nose gear on landing, this wouldn't really apply, but that would be another topic, wouldn't it?
