I disagree that the revolving-door is equal to regulatory capture. While it may be a precursor, we do already know that supply-side policies like putting a time-lock on the door is a remedy. Note also that the door would be locked for industry to hire from the government agencies.
Revolving door people are no better apprised of "the issues at hand" than someone with a (e.g.) buy-side foundation. That's one of the places where you filter out alternatives, by assuming that the revolving door candidates are the ones who "actually understand the issues."
You also continue to perpetuate the dichotomy you said you weren't making by refraining from even acknowledging a middle ground, so maybe this is just a case of mauvaise foi on your part and poo on me for engaging.
