You sound a bit like one of the engineers you sometimes argue with here. The kind of engineer that wants some area of law to be a black and white rules based system where everything is decided based on a perfectly clean application of logic. But you know that's not how society works. And it's not how the law works either. There are tremendous grey areas in which rules try to balance competing interests in a way that ends up being, more or less, fair. This balance is based on ideas of messy humans and the culture we've built up over thousands of years. It's not cognitive dissonance when we end up with a rule that is bases on more than the precise scientific inputs. It's just the way our law and culture works.
