I'd say it's usually that there's a small, immediate negative effect of losing the object, but a larger-over-time positive effect of not living with clutter. I suspect most people run in to up-front-costs issues, and also don't realize how much of a negative effect clutter can have ("it takes an extra 2-3 seconds to find any utensil while cooking; therefor cooking is less fun; therefor I cook less often" style chains seem fairly common)
