This is a great way of looking at it and while I would never do it anyway, is all the more reason for me to not even consider doing it. If you have ever known someone with a genuine disability, it boils your blood a bit when the fakers want what they maybe consider to be special treatment. A person who is genuinely disabled would likely give anything to be sitting in a normal seat and getting normal treatment in exchange for not being disabled anymore.
I read somewhere that some airports are considering getting self-driving wheelchairs because they can no longer afford the army of wheelchair pushers and golf cart drivers.
