Also there are a lot of crypto-millionaires that believe this is the future. So that's why they are going for large sums so soon. I am not one, but I do think they are right.
It's not even ownership, at least in the classic art collector sense or in the sense of having a meaningful degree of control over the work. Torres retains ownership of the copyrighted work. What he's selling is a transferable limited license that doesn't even include any commercial use rights.
What's a little mind-blowing to me is that the terms of the site don't indicate that the license is an exclusive license. The buyer gets no legal guarantee that Torres won't sell another such license in the future.
The nyan cat image is out there, copied all over the place. The buyer isn't getting a commercial license or anything like that.
I'm really not sure what the buyer is getting here.
