I absolutely think that digital art is as valuable and worthy of recognition as physical art. My wife is an artist (oils and water colors, not digital) and we've discussed it at length that the skill and talent required to create digital art imparts equal value. I'm not arguing against that (I'm not saying that's what you're saying either, but just to be clear for folks who read the comments).

But...I do not see the value in being able to "prove" that you own said artwork...because you can't do it...Globally, the number of people who know what Ethereum or any other block-chain technology means is probably what..many thousands? Maybe..maybe a few hundred thousand? And of those the subset of people who actually care...I'm sure is far fewer. So you can only verify yourself as the "owner" of said art to a very small subset of people...

I guess it's like a collector community? People are willing to spend literally millions of dollars to prove to other collectors that they are the owners of these digital assets?
