I don't see how not having a DVD player is supposed to be a fault in the Gamecube's design. I own about three DVD players, and frankly, I don't need another one taking up space in my GC. The Gamecube is solely designed for games, and as such, the technical quality of most games on the Gamecube is better than what can be found on the PS2.

So, yes, you're paying less for a GC and not getting a DVD player, but you are getting a more powerful console, and one that will last a lot longer.
