OK guys - come on, Sir Moody has it right but missed the point.
You can't fight a knight until you are 21 because you can't match him in heavy armour, so you can't fight for yourself.
The point is, at 14 Rob is far to young to be able to wear full plate and fight, Sir Loras at 16 likewise. Those painting you see of boy-Kings have them in fake armour much thinner than the real thing - that's fine for Joffrey playing soldier but it would put Rob or Sir Loras in a position to have their chests caved in.
