MAC
Addresses are hard-coded right onto the Ethernet device with a company specific
ID and a series of codes. From what I understand it is impossible for any
device to have the same MAC as anyone else. As far as changing a MAC,
unless you are changing the device you aren't able to do it. If you were,
it would make IP spoofing and hacking a hell of a lot
easier.
As
far as why do you have a MAC? Like others have mentioned, having a
registered MAC (with the manufacturer) allows your device to communicate with
others, as well as giving a way for your machine to be identified. This is
beneficial for firewalls, and other security devices as they may be able to
filter and limit access by a MAC address.

I don't know of any advantages to being able to change your MAC address; all ethernet devices have MAC addresses specifically assigned to them, each one is unique- though I'm sure there have been duplicates before.
