"Just close the loophole" to me sounds like "just fix the bugs" in an API used by every person in the country. That would be an enormous undertaking, not something you "just do". Most likely many benign people rely on particular combinations of these rules such that changing them might have terrible consequences for them. And some loopholes are likely similar combinations of rules, and removing those might create others unexpectedly. An expert weighing in on the specifics would be nice, since I'm just speaking in vague generalities b/c I don't actually know the specifics, I can only compare it to my experiences in software. I'm also not arguing that it's not worth doing, just that it's probably not as easy as "just" doing it.
