This argument is silly on all accounts. But let's look at this in generic terms, of gun control and vehicle control. In some states, anyone with a pulse and over the age of 18 and go into a store and purchase a firearm and use it that same day without breaking any law. They could even, and sometimes do, go and shoot someone in the dick or face. In no state can you someone purchase a vehicle and drive off the parking lot the same day without a license and car insurance, both forms of documentation somewhat insuring that the person is responsible, and will likely not go off and drive over someone's dick or face.
