Yeah, you could do that. There's not really much difference between launching it with X and just configuring mpd to run as your user, though launching with X might be easier to setup in some cases.

The only problem with that approach is it means that mpd is tied to your X session. I quit or restart X every once in a while and it's nice to have my music keep going during that time. But obviously that's not a use-case everyone cares about since most people don't have a reason to leave X.
