Yeah, I guess that will work against the whole idea! Last year I had to clear out a house of a family member that passed away. We ended up putting everything in front of the house with a sign "free to take". I was surprised at what people took. Something that has no value to one person means the world to someone else :)
After thinking about it for a day (I mean the 40-day clutter challenge), I'm actually realizing I would be able to do this for 40 days! I'm considering following your example :)
