It seems to me that the problem here isn't someone running around the airport making up stories of their flying experience. The problem is a pilot and command willing to yell "You have control" to someone and let go of the controls.
I have had to explain to many students that if something goes wrong, yelling "You have control" is not an option. I'll take control if I need to and you'll know I'm taking control. Until that point fly the aircraft.
