Roy, you speak with a self certainty that would come across to some as having authority in your opinion. That's what it is after all, an opinion. It seems like a logical conclusion....
If you go back a bit and start looking in to the history of photography as fine art, there are plenty in the higher end world that consider it an art of multiple originals, which makes sense. The end game is the print, therefore the digital file can be considered as a step towards completion of the end result...the print. I can't see a reason why this can not apply to digital art also.
Susan, all you are going to get here on this internet forum is uninformed opinion. It's like asking, what is art. You will get people defending their positions with absolute certainty and an unwillingness to give in to their positions or even acknowledge other viewpoints. Even for matters that are accepted and agreed upon by those "in the know", you will still get people sticking to their own viewpoints.
There is nothing wrong with just calling it "digital art".
