And the problem with this is ... ?
Folks, the problem with smoking isn't that it just puts you yourself in medical danger. Or even puts a burden on your family. It also puts a burden upon the rest of society. Through:
1) the dangers of 2nd hand smoke, which has an increasing medical evidence of the risk to other people.
2) the increasing medical costs to other people, particularly when the smoking patient is uninsured. Thus sending the costs to you and me.
3) the health effects that is on those that smoke often makes them less efficient, less productive, and invariably puts your fellow workers at the risks given above.
4) since smoking is so damn addictive, it exasperates the problem, and again, often on the backs of others, not just upon yourself.
Guess what, boys and girls, at the risk of sounding like an e-v-i-l Marxist, liberty is not something that is solely the benefit for you yourself. Liberty comes with responsibility to have the regard for other people. ... No option in that. Liberty for yourself and regard for other people are like Siamese twins; cut one off, and the other dies.
Like my mother would always say, "You live in a world with other people." ... Oh, and as regards to all those other items that people can possibly be harmed by; sugar, booze, etc., ... legal products they might be, but if the usage of said products causes harm to come to you as well as puts a burden on society as a result, then yeah, your 'liberty' as regards using such is going to be curtailed to some degree.
