The only way to get Adam Smith style markets is to forbid, and enforce the prohibition, corporations that are a large fraction of the market. No Walmart, no Amazon, no Tesco, Sainsbury's, Morrisons, no IBM, no ARM, no Toyota, VW, or Ford. Ownership structures that hide the actual owners would have to be rooted out. That way we might get slightly closer to markets where both suppliers and customers have a choice as to who to deal with.
