When you turn it into a binary "we need to stop them from absolutely sharing any privileged information" or all is lost, it's an unsolvable problem. Alternatively a few achievable steps could make a large improvement: - Force them to put everything into a trust that they don't have direct control over for the duration of their term vs. allowing them to make trades and disclosing it eventually. - Have enforced laws on sharing information, and actually send people to jail a few times a year. Skew the risk / reward. Let people think on if they want to go to prison.
