If ownership is the key factor, rather than direct or indirect purchase, then you get some odd results.
First, what of a person who becomes the legal owner of a stolen book by buying it at a market overt?
Second, what of a person who becomes the legal owner of a book gifted to him by a person who originally purchased it legally, and first used and copied it for his own purposes before passing it on?
