Artists get paid for building a brand around their creations, not for making loads of pieces of the same thing. If someone were to copy one of his paintings, it would clearly not be of the same lineage.

I think many novelists, filmmakers, photographers and songwriters would disagree. Piracy can affect their ability to earn a living from their work. Few regular people care about the "lineage" of their ebooks, digital photos, audio streams, video files, or mp3s as long as it's convenient and allows them to enjoy the artist's work.
