This law is true on a bigger scale as well. The more you have in your life that's extraneous, the less time and energy you have for good stuff. Dust loves stuff. Bugs love stuff. Rodents love stuff.
Moisture loves stuff.
It takes time and energy to put things away. That's why the coat or sweater that's flung over the chair tends to stay there forever. It would follow then that the easier you make it to put stuff away, the more likely it is that it will be put away. Stuff expands to fill the space available. The bigger the house and the more storage, the more stuff accumulates.
