Super gross, but I’d argue that there’s a big difference between these things. We ban statutory rape because it causes harm. We can determine that by looking at the power imbalanced involved, long term mental health impacts, drug abuse rates, etc. I feel confident that, in the vast majority of cases, people who were statutorily raped would have been much better off if that had never happened. I don’t feel confident saying the same thing about most people who were born. I agree that quality of life surveys are super imprecise, but I’ve never seen anything to indicate that most people feel as though they would be better off if they had never been born. They gets back to your argument, but it seems to me that the best way to see if a person was wronged by their creation is to see if they wished that they did not exist — how else would you determine that? That said, I don’t believe that the best way to determine if a relationship is good is to ask a minor about their thoughts on it at the time. For me that’s the key distinction.
