Exactly. The libertarian talking point that the market and private entities self-regulate because consumers "vote with their wallets" is nonsense. If people are misinformed or not informed at all, then people don't have any choice at all in what is supposedly a free market! As I mentioned in another comment, we know many companies do not disclose what they put into their food products, and this is in spite of regulations also still existing! The Tesco supermarket chain in UK turned out their beef meat has horse meat and none were the wiser until it's too late!
