I didn't downvote, but if I had, it wouldn't be for that reason. It would be because having kids or not having kids is something many people speak of cavalierly as if it is totally in our control and this is often not true. If birth control fails, there are places where abortion is hard to come by (including large parts of the U.S., from what I gather). These attitudes disproportionately negatively impact women.

Much of human sexual morality is rooted in the thorny issue that mother nature makes sex pleasurable in large part to get you to reproduce and efforts to enjoy sex without it leading to babies are often unsuccessful. So, we have a long human tradition of things like shotgun weddings.

No, people don't like solutions which ignore the problem.

Yes, by completely changing your plan for your life you can prevent certain problems, but that doesn't necessitate that you should make the change.
