The problem is that you can't be sure that if you use RFC1918 today you
won't be bitten by it's non-uniqueness property in the future. When
you're asked to diagnose a fault with a device with the IP address
192.168.1.1, and you've got an unknown number of candidate devices
using that address, you really start to see the value in having world
wide unique, but not necessarily publically visible addressing.
