It doesn't explain the desire to. The reason behind the desire to fill your lungs up with cancer? Does it taste good? Does it smell good? Does it feel good? *sigh* why must everyone force the concept "oppression of liberty/freedom" on everything? I don't have a personal crusade, I just said I don't understand it. (I'm seriously so confused right now why you think I care enough for me to go on a crusade about it.) I honestly don't give a shit what you do in your private space. If you do it in public, I have a right to object... If you blow it in my face, I'd probably deck you. If you can get arrested for running around naked, there could certainly be some regulation regarding where you smoke, it being an actual health hazard (eg not public indoor spaces and not near doorways).
