Sometimes relaxing regulatory measures leads to people following them better, as they better match the intent of the regulation rather than being seen as absurd. It also lowers the 'benefit' of deviancy from that regulation.
Sometimes you're right, you regulate more extremely than the intent because people will follow it better, or it makes it easier to enforce.
The point is there's not a one size fits all.
Yeah I don't believe most of these are real "big taboos" and will continue eating food the way it is most tasty to do, regardless, thanks.
