I'd like to emphasize that this incentive doesn't have to be an accidental find by the insider either: The "market" can end up facilitating anonymous crowd-sourced bribery by enemies or competitors, who create the potential for profit knowing that eventually an insider will take the other end of the implied deal.
Every time I see someone dismissing these kinds of issues--especially someone whose salary depends on not-understanding it [0] --I imagine how their tune would change if the shoe was on the other foot. For example, if someone created a "prediction market" where people could anonymously bet on unusual deaths or serious injuries of... prediction-market executives.

Actually, now that I think about it, let's get rid of the minimum, there should be no minimum, all bets even five cents must be fully disclosed and attributed to natural persons, no hiding behind "corporations are people, my friend" nonsense.
>>the real danger of insider trading are company insiders being incentivised to damage the company to make a quick buck.
Damaging the company is illegal as well. Making things illegal doesn't magically stop people from doing what they have incentives to do.
