There's nothing stopping it from happening.
ZOS is well aware of this, and as far as I know, it's not explicitly stated in the TOS about arranging a Crown Store gift in exchange for gold. Which makes this situation very murky.
ZOS really needs to come down on one side of this fence or the other. By being indifferent and silent on the issue, they really will encourage scamming. If ZOS doesn't want "CS gifts for gold" in their game, then they need to amend the TOS to make it illicit.
If they aren't going to make "CS gifts for gold" illicit, then they should just go the full measure and make it possible to trade gifts within the trading UI and/or COD them in the mail system. People are probably already going to do it whether ZOS says so or not, in which case the least ZOS could do is make it more secure and take control of the situation.
Either way, it would be better than the silence.
