I don't entirely disagree with your post but I generally avoid calling these loopholes. It is all about finding the mismatch between two countries --
For example, if a little kid asks his dad if he can go to the movies, and dad replies "go ask mom, do what she says" and the kid then asks mom and mom says "whatever dad said" it doesn't mean that you are necessarily finding a loophole. Either party is essentially deferring and the benefit is caught in between. Works out well for the kid but at the end of the day, the parents probably should have had better communication and figured out what to do.
