There's a difference between going out and buying new stuff and not getting rid of existing stuff. The first costs actual money, the second only costs space. Depending on how much space costs relative to the stuff that's stored in it, keeping stuff around might be perfectly rational or even optimal. It's not guaranteed to be so by any means, though.
