When you say "free market" you imply that there is zero political risk (meaning risk of politicians using their elevated powers against you) resulting from their choices.
In reality there is political risk for highly public decisions. Politicians do have power. They can call you before Congress under oath without any evidence of legal wrongdoing by anyone. They can start costly antitrust investigations. They can start costly audits. Anywhere along the way, if you make the slightest misstep (or even if you don't), they accuse you of perjury or lying to a federal official or obstruction of justice. Or maybe they just don't "protect" you as well as they might from various unfortunate events.
Moreover, there's a pattern of governments harnessing the power of private companies to various purposes through this kind of coercion. If you are a CEO with a comfortable life do you really want to test the ideal that it can't happen in the U.S.?
