So if I happen to have guns for boobs, and I go around topless showing off my gun-boobs, am I a magnificent symbol of liberty or am I deplorably degenerate?
Items require payments which usually would be a credit card. Kids cannot get a credit card on their own as far as I know so the parents have to be involved in some way. (Obviously there are alternatives like paypal, prepaid debit cards, etc but it is quite a bit harder to actual get the item).
I am not saying it is hard to get a prepaid debit card. I explicitly mentioned it as a workaround. I am saying that it is harder to get buy a physical item over the internet then to just visit a site.
