As a product, it should first be widely sold, and *then* advertised, so if the authorities try to crack down on it there would still be lots of it on the street.
Its biggest application would be against unarmed harassment and intimidation. Its purpose is “counter-intimidation”, as in, “I am not your slave, nor will I be your victim, you pig.”
