I think you are missing his point, which I take to be that the market cap reflects a lack of insight--because most owners lack both the industry and the information to obtain it--whereas a suitor would have made a more thorough study of the matter, being better resourced and more highly motivated to weigh our prospects with sober care and in detail.
