That sounds orthogonal to device management to me. It will happen either way, and not having GPS tracking won't stop parents from catching their kids doing stuff they don't want them to (at least if it's a recurring thing)

People here seem to completely overlook that parents have been managing the whole life of their kid for more than a decade and teenagers are really bad at hiding things in general. Perhaps it's different if the parents are working three jobs and never talk to their kid, but I don't see that as a general case.
