Some people steal even when they can afford the things because they have a disorder. It's like an addiction to the thrill they get when they steal something from a store. This is what happened to Wynona Ryder. Lynn Anderson probably has the same disorder and her stealing a copy of PoA and being caught was most likely just coincidence. I would bet that this isn't the only thing she has stolen, and that she didn't do it just because she's a 'giant hp fan', so I would hesitate before going so far as to call her an 'idiot'. Yes, she broke the law, but there's no need to assume things before we know all the facts about why she stole it.
