What stops you from making this argument to allow kids to smoke cigs? That's kinda how this is. Imagine if every kid smoked, and if you didn't want your kid to smoke too, they become a social outcast with all the mental issues that come with it. Society steps in to regulate harmful/predatory behaviors all the time, even between consenting adults (let alone children, even if their parents play along). Libertarianism just doesn't work for kids. (I think it doesn't even work for adults, personally)
