It was something about that companies have to make some kind of protection. If not for anything else, just for setting apart the legal and illegal versions if there's any chance for any level of jurisdiction. (copied it from an unedited post of mine).
If you are going to take people to court for pirating the game -- which is unlikely -- then proving that you implemented both detection and countermeasures can help when it comes to the judgement.
Several laws require that there were effective deterrents in place, no matter how minimal they were. Basically it's the difference between stealing an unlocked bike vs. stealing a bike secured by a simple lock; the second is considered worse because the action required breaking a deterrent.
Unless the OP is part of a business he is unlikely to ever encounter it. If the OP is part of a business that is willing to spend the fortune in suing pirates then it becomes a question for management to discuss with their lawyer.
