Privacy addresses don't hide what's on your network as much as NAT does, which is what the GP wants. For example with privacy addreses, monitors outside the network can easily see you have 5 devices on at the same time, 4 of which connect to port 443, 3 of which connects to updates.microsoft.com or whatever (just an example). With NAT, monitors outside the network can see the connections, but cannot see (from IP/port information alone) that there are 5 distinct devices and what they individually connect to.
