On a shared newtork, even if you have the physical
(MAC) address which is at the data link layer (2), It
would still be hard to pinpoint the location of the
device on the network.

For the most part, there is a 1:1 relationship between
Layer 2 and Layer 3 (IP and MAC).. So for our purposes
of the privacy discussion, they are pretty much
interchangeable.
