I don't think this argument really matters. Consumer drones are being used in active warfare today, as we speak, with minimal modifications. The cat is out of the bag no matter which way you look at it. You could just as well say that many chemicals at the construction store are easily weaponizable, they make for an explosive and there's plenty of guides online on how to do so.
Even with access to explosives, you still need a bit of gusto to carry out the rest of the crime. I think it's a bit different when you can ask the weapon to find and eliminate its target without you ever having to leave your garage.
Not being a high profile target myself, I'd rather take that risk and see where it goes. Unfortunately it's the high profile targets themselves that make the decisions, so after the first few incidents I figure there will be this whole mess where they try to clamp down on access to such things without sufficient forethought.
