No one would dare drive down the street if they couldn't trust the other drivers to stay on their side of the road, to stop at traffic lights and stop signs, and follow all the other laws governing driving. The laws bring order and control to what could be a deadly environment. In fact, deaths and injuries usually only occur when someone disobeys the law. Clearly, following rules, obeying the law, and doing as you're told is important to your life. Without getting overly political, you begin to lose your personal freedoms and liberty.
History is filled with stories of oppressive governments that took away personal freedoms.
Government leaders wanted to control every aspect of their citizen's lives, from the jobs they held to the thoughts in their heads. At first, you were in control. You would smoke only when YOU wanted to. You smoked when and if you wanted to. And you probably had to really WANT to smoke when you first started, because it tasted so bad and burned your lungs too much.
