Your abortion thought experiment may be backwards: aren't we protecting the fetus from future harm by aborting it before it can comprehend or experience the multitude of harms it's bound to experience in life? Taken to the extreme, this idea of preventing harm would compel us to have abortions. Of course, that's just not what anyone is saying anyway. Like with many legal constructs, there is an implied "within reason". For example: the U.S. constitution's first amendment and "shouting fire". You're reading way too literally into the concept of "duty of care" or "future harm".
