If so to what extent? I know libertarians who say that in the name of liberty, we should be allowed to become a nation of blimps. The two big issues I see today are smoking and obesity. Although if you asked me about the concept of Big Brother in general, I would respond negatively, however it seems that the government is the perfect entity to push against this kind of negative society level changes like a 25% obesity rate. For smoking, is having a huge tax on cigarettes a valid means of achieving this goal? I think so, although I might not like it *if* I wanted to smoke pot and the government levied a huge tax against it. How about fast food or huge portions? They are all ready involved in elementary school diets. Where should it stop?
