In an "art market" context it makes sense. I can print a copy of Warhol's Campbell Soup labels, but that doesn't devalue the original, nor is my copy as valuable as the original.
It's not about copying the pixels, it's about showing provenance.
But surely, the thing that makes Warhol's soup cans more valuable than a copy is the fact that Warhol (or his studio, anyway) actually touched the original. Being able to show provenance isn't what makes it valuable, it only shows that the particular thing in question is the valuable one.
I can paint something right now and show provenance for it, but that won't make my childish scrawl valuable.
The problem with electronic art is that there's nothing special about the original over copies in this sense. You can't hold it and know that you're holding the very thing that the artist was working on.
And the fact that a painting is not reproducible. The best you can get is close to the original, but it will still be different because its the real world. Copies of digital assets are exact replicas. Thus, the only real value is, as you say, provenance, but I think much fewer people care about that than we all seem to think.
It's not about copying the pixels, it's about showing provenance.
