That doesn't really solve the problem because how do we make them become monks? We already have a blueprint on how to hold them accountable: hold them to the same standard as those working in financial services with access to PII. Essentially make it impossible for them to be active traders; they can even still invest in ETFs and hands off advisors/roboadvisors like Betterment.
Even then, do you want people who are incentivized to pump-and-dump the macro market during their term? You'd almost need to enforce this for 10 years or more, even if it goes beyond their term.
