I Am Large, I Contain Multitudes

Yep. In my work, I also try to get my clients to think about expanding the idea of a "supply" to include not just stuff in one's home, but stuff that just takes a -little- more effort to get. For instance, there's no need to hoard plastic shopping bags, because it's easy to get more whenever you go shopping. Libraries have an inexhaustible supply of books, so you don't have to try to fit all those books into your house. And so forth!
