I think your comment got an unfair downvote. The rant was okay, but it went on to talk about a strawman argument of a measure(beef consumption) before flying. However, the better I'd have put the whole rant(not sure OP agrees, this is just my reading of it), is like this: We've been reactively forming policies out of fear of extreme bad/negative consequence events. Since, the time window of public/societal memory is limited and there's a cycle of elections and power structure climbing too involved, the policies tend to be ones that are sellable/explain-away-able to the vast majority of the public. And these become the standards till another event occurs and never re-considered.
