I think the expectation that the entire consumer market (or even just a majority) is going to collectively become universally informed about all their purchases and shift the market for the better is far less likely then a government intervention being successful.
If you go to countries where there was never any government intervention relating to cigarettes do you know what you'll find? A lot more people smoking cigarettes.
