I disagree with the last point -- it's a pain to gather a bunch of things up, put them in vehicles (or rent a truck), find a storage facility that isn't full, rent the unit, haul your things over to the unit.. all the while ignoring that you're putting off whatever culling and disposal ceremony you should actually be engaging in.
My local town gives you two free visits to the garbage transfer station per year. Choosing storage over that seems harder.
