Most people's diets and lifestyles are so harmful that adding or subtracting a little salt will make little difference to their overall health. For example, some people I know are overly concerned with whether their vegetables are organic or not, completely missing the fact that they live in one of the world's most polluted cities. IMO, getting caught up in the details makes one lose sight of the overall picture. Oh, and enacting more laws is surely not the way to advocate personal responsibility.
