What's to stop the user from crushing someone wearing metal armor like a tomato can? Don't say Aura because people don't infuse their armor with Aura actively. Look at Jaune. Pyrrha slammed him to a wall by his armor. I asked on the Weapons thread about Aura, and Vedran mentioned that anything the person touches is passively infused with small amounts of aura, which would restrict him from using the Semblance. Whoever touches the item most has the most amount of Aura in it, and if he has less aura in it than the opponent, he can't manipulate it.

and if you want something else, I could pull out the old "Moral Restrictions" trick, but I really hope the above argument holds water as well.
