Generally when the artist endorses it. NFTs give you a token that represents a piece of art they made which you can move and resell independently, even if the artist is no longer around. I personally am not very likely to buy any, but I can see the appeal (it's much the same as owning the originals of any other bit of art as opposed to a copy). The current cost of creating and moving them around is unfortunate, however (and reflects the immaturity of crypto as a whole. I believe ethereum is working hard to improve their scaling with a plausible plan, so this should improve, but it is a definite problem at the moment)
