Government subsidized health insurance

If we do end up with gov't subsidized health insurance, or universal health care, does that mean, when I see a person smoking or eating too much, that I should be able to tell them to stop, because they are affecting my taxes? While I do believe everyone deserves fair treatment and health care, this method seems to reduce personal accountability and will force people to try to get others to stop.

The goverment helping health care and having others keep individuals accountable have the potential for better national health, but again, at the expense of individual freedom, much like a smoking ban causes.

Thoughts?
