I think there is plenty of privacy in just getting in touch occasionally.
My son was going to be in mountains with no way of contact for 10 days. I can't see that it was constant monitoring or lack of privacy to let us know that he was back in civilisation - after all someone needed to know that he wasn't lost with no phone signal.
I suspect that it isn't a problem. If you have brought them up with roots and wings and to be independent they are going to do it anyway. If you are constantly interfering and controlling or have no interest then they won't.
