So it would be ok for me to poke people with a thumbtack wherever I go? After all it doesn't cause much damage and they could just go somewhere else.
What the heck? That's an absurd analogy.

Since when is there anarchy in personal property? Each persons house or establishment is not their own country. They are not totally free to do as they please; they cannot murder other people on their own property, or dump poison into their earth above a water resevoir.
Smoking on your property doesn't affect anyone else, unlike everything you listed. Duh.

There is a public health interest, and it should be served. Nobody is denying them the right to smoke in their own homes, but a home is much more personal than is an establishment that is meant for other citizens to sit in for profit. It obviously effects others, and the majority of people no longer wish to sit in smoked filled rooms that are only smoke filled because of a minority.
Oh please. The 'public health' is not being affected by smokey bars. A privately owned establishment with smokers does not affect the public as does pollution. It affects the people who go there to drink and smoke. If the majority of people don't want to sit in a smokey room, DON'T GO THERE DUMBASSES.
Let the profit motive force the bar owners to change policies, if there really is such demand for change.
