Doesn’t more room in general and that for storage a catalyst for creating more “stuff”?

When one thinks about it, how much stuff does one really need? How much stuff does a person have they really use? Why starting my spring cleaning super early I got to thinking about what some said in this question, about wanting to have more cabinet space. I have heard people say they wish they had largest garages or closet space. Depending on where you live it might be small, but many of the houses I do work in are twice as big to three times the size the ranch style home my aunt owned. With all that extra space doesn’t it beckon to be filled with something? People who have a three-car garage but only one vehicle, do they leave that floor space open or do they somehow fill it with “stuff”? If you moved to a large house, with two extra bedrooms, if you did not make one a guest room, would they both remain empty or would you have to justify them by putting “stuff” in there? If you did put something in there, if you did not have the extra room, you would still have what you put in there, it would have just been somewhere else, and so it is not like that extra room was the only place it could have gone.
