Or maybe lawmakers are just tired of seeing loopholes abused by unscrupulous people. It's like banning shark fin, it just gets taken off the menu but can be ordered in mandarin.
If shark fin is illegal, then being able to order it in Mandarin isn't a "loophole" -- it doesn't magically become legal on a technicality.
It's just a means of avoiding enforcement of the law, by making the illicit activity less obvious.
People will find loopholes anyway.
It's not even hard in this case.
