Not saying that it's pointless (yet) to do so, but it sure seems headed that way.
At some future stage, all of this enforcement will not be worthwhile or manageable anymore.
The one thing that comes to mind is Gabe Newell, who proved that piracy is only a problem when the stuff isn't easily available. One could wish that publishers would come to their senses and roughly offer everything in a similar fashion to what Steam has been doing with games.
