Ana: On libertarian principles, I oppose the proposed smoking ban. It is not the government' s business to prevent people from doing things that harm only themselves. Pankaj: But keep in mind that the ban would apply only to smoking in public places. People could still smoke all they want in private. The dialogue provides the most support for the claim that Ana and Pankaj disagree over whether ['government should be restrained by libertarian principles', 'the proposed smoking ban is intended to prevent harm only to smokers themselves', 'the proposed ban would prohibit smoking in public places', 'there are cases in which government should attempt to regulate private behavior']
