And they probably literally couldn't. At the time they were connected to the weapons. We know the original 4 ninja's powers depend on Lloyd, so it seems their powers work on different logic. actually my guess is since there wasnt a green ninja during the era of the golden weapons, they had to rely on the weapons, but after lloyd became the gold ninja the ninja got their powers from him
