It's easier to justify stock markets banning insider information because there are ignorant participants through their investment funds who we would like to protect. Why would we protect willing participants betting on arbitrary events? Even if we ban on this one too, should we in general be able to create a market that explicitly allows insider information for some arbitrary thing, insideinformationverywelcomemarket, where everyone is aware it's the main point of the market or shall we just protect these people from themselves?
