There was a comment I saw the other day along the lines of "Science will tell you what the numbers are, but doesn't make a judgement of how big that number should be."

You can get a pretty good estimate of how many lives would be saved if we smoked less, or drank less, or did any number of other things, but ultimately that's an input into a public policy decision making system that doesn't have a provably right answer unless everyone involved agrees on what the desired outcome is.

Nobody is enforcing anything, either in the parent or the OP, so don't panic. Your comment seems inflammatory and irrelevant in this context, but I'm sure that's not your intent. You'll be ok, don't worry.
