They're not really teethed though. I grew up in DC and new plenty of parents who were ex-chief of staffs or whatever and they literally would tell me that they were working for a lobbying firm as a "consultant" because that was a loophole for getting around the "can't join a lobbying firm rules."
Nah, you just shut out good people who want to do good things but can't figure out rules or feel like the burden to doing good things or the potential penalty on technicality or slipup isn't worth it, and select for sociopaths who are adept at figuring out how to use rules (especially draconian ones) to their own advantage, spirit of the rule notwithstanding, because they WILL put up with the burden and the risk.
It's not really that complicated to not work for a lobbying firm for 2 years after leaving a chief of staff position for a Senator.
Nor do I particularly want people too dull to figure out those rules to be making laws for our entire country?
