I know exactly why it is-- it's part of the whole fantasy of Better Living Through Stuff. Like if I just get the _right_ stuff, all of the clutter in my vicinity will just vanish, and be replaced by perfect organization (and sparkles and rainbows). The recycling will dispose of itself; the paper will stop multiplying exponentially every time I turn around; the living room will stop being the place where clutter goes to die....
It's the concept of having a completely clean slate-- like moving into a new apartment/house and having to go and buy everything. Or at least mostly everything; clothes and books would be there, but everything else would be finding new stuff rather than having bits and pieces of old stuff uneasily coralled in cupboards, etc. I think this happens to practically everybody, really.
Of course, my brain wants to turn it into a story.* But that's just me.
*It keeps trying to generate first lines.
