Supposing you're right, then why did they put these loopholes by purpose if they're going to be discovered someday ? To play games with us maybe ? But then is that morally ok to do so ?
Before asking why the loopholes are there you should ask why the laws are there, then you can ask how the loopholes fit into that purpose.
Speaking as an Orthodox Jew - We believe the laws are there because particular actions affect the universe in ways we might not understand but that the creator does. It's like the instruction manual that comes with a machine. (If it was something we could figure out for ourselves we wouldn't need to be given the laws from on high.)
So it follows that if there is a loophole, in a law given by an omniscient God (i.e. there is no argument that He didn't think of it), it's because following that loophole does not cause the spiritual damage to the universe that breaking the rest of that law does.
Obviously some of you will argue with some of those axioms, but as stated by WJW elsewhere in this thread, this is about people who have already accepted the axioms.
I should add that there are those who study how each thing affects the world - that is the study of Kabbala.
But you don't need to know it to accept the idea, just as you don't need to know how a machine works in order to use it, as long as you follow the manual.
I can't claim to understand everything, as he apparently moves in mysterious ways. However, just from the definitions we can deduce it's morally OK to do, since otherwise a perfect being wouldn't do so.
To play games? Perhaps, but presumably a perfect being is already perfectly happy and has no need for games. You could see it as a test for humans: only the truly devout study the laws closely enough to notice the loopholes.
