My thought is that saying someone can't work in the industry for 5 years prior might help with breaking up regulatory capture to a certain extent, but could have consequences on the people filling the role actually understanding the issues at hand.
Your view seems to be closer to, "things are bad now, so we certainly can't do any worse." My view is that if we're going to make the effort to fix things, let's think things through rather than throwing things at the wall to see what sticks.
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.
