Alcohol and stupidity in general are just as dangerous, and are far more likely to kill or maim not only yourself but other people as well. So should we ban all alcohol use for your reasoning?

By that logic, what else can we outlaw? Why, everything! Religion, guns, money, thinking, breathing, living....
