I would think that it would be fantastically easy to kill someone with just poitions on them. If you are facing an Akali in lane and you are afraid of this situation a bunch of things could have helped you stay in lane longer. Buying some Mana potions and health potions as well. Yeah unless you have spell vamp already on you. You might as well just let the scaling AP and the starting AP you have work for you while buy some more conservative things. Farie charm and the bead help a lot more than you think.

Another thing. Clarity. Seriously. In that scenario where Cassopeia and Akali hash it out and Akali manages to somehow bail and return to turret to heal. You swallow a Clarity. Rush her at the turret and finish the job or make her health so low she'll retreat to the fountain (even with poitions most players will recall if they think you can safely dive them).

Restricting the poitions wouldn't be as effective as just punishing people for not wearing boots, Armor, or a token Doran which would be far more protective in lane.
