There are many people permitted on aircraft now with a variety of disabilities that preclude or restrict their ability to get up and move around the aircraft on their own. So, your argument isn't going to hold up as primae facie evidence in any hearing on this matter. This specific rule will have to be tested as a unique safety concern and given previous CTA rulings it will be examined seriously.
