Well, not if you interpret "stealing" as "misappropriating," but I don't think the quote is quite that literal. My interpretation of it is that good artists "borrow," that is, they take elements from others but they still belong to others. Great artists, however, "steal," meaning that they take elements from others and make them their own to the point where we start identify those elements with the "thief" instead of the originator. Someone who succeeds in doing that is probably a pretty damn good artist.
