I realize that many players just prefer 3rd person camera. Still, my arguments have an objective grounds, namely the problems that I described, whereas your only argument is a personal preference. I think Oblivion got it right, when it gave you a choice between 1st and 3rd person camera.
I really do agree with some of your criticisms regarding the way 3rd person view works in DKS. Theoretically, those technical shortcomings could be 'fixed.' After that, it all boils down into a subjective debate.
Subjectively speaking, I still find it awkward playing games in first person view, I always have. I just like seeing what is all around my character - that peripheral view gives me such a great sense of visibility of the area my character is standing. It's true that you can abuse the camera mechanic to see things your character cannot, but it's something I can live with.
Objectively, I would never say that 1st person view = lesser and 3rd person view = better. But my view is that every player has a natural comfort level with one or the other.
I agree that Oblivion got it right, allowing you to play in 1st or 3rd person – that way each type of player can just play the way he or she wants to play. I just hope that Skyrim will improve its 3rd person view mechanics as Oblivion's implementation of 3rd person view was weak.
Also, if you're interested, I wrote my own impressions of DKS here a few weeks back... it has dropped off the first page of this forum already, but you can read it
