I'm not sure I see the same point as others. But the way I imagine it would work is that you buy art from the artist and the artist confirms (on the blockchain) that you bought it from them, thereby supporting them. So (a) you "own" it, (b) you signal being a patron of the arts and (c) the thing you paid for can be enjoyed right next to this confirmation. Yes I guess it can apply to other things as well. I would indeed expect books and movies to possibly fit the same pattern. And I guess you could set up a public sexual partners log as well where both participants can use their private key to sign a statement that they did indeed engage in intercourse but I'm not sure that that would take off :) I think the point is still being discovered and it also seems totally possible that this is just a fad. It's the first practical application of cryptocurrency that I can somehow see making sense (if I squint).
