Isn't the idea of being unarmed moot if a person can fight?

I think the idea of people being defenseless (women, children, etc) is stupid since the human body can be a weapon is someone throws a punch or kicks a leg so that someone trips. Not carrying a firearm doesn't mean a person doesn't have a lethal means of inflicting pain or physical damage. Anything can be a weapon if it is thrust forward with enough speed and makes a firm enough impact on the human body, be it a fist or a baseball or a penny or a tree branch. So in that sense there are potential weapons all over the place. They're not solely metallic (a.k.a. guns, knives, swords). They can be wooden or glass (cracked beer bottles) or even the human body can be a lethal weapon (connecting on enough punches and kicks that someone dies or wrapping the arms around someone's neck so that her or she has all the oxygen choked out of them. Even water can be a weapon. A person can die from not drinking enough of it (thirst) or of being suffocated with it (drowning). Funny how we can't breathe in it, yet it makes up most of our body and we must drink it or we die. So in that sense even water can be a helper or a harmer to humans.
