I believe OPs point is that supply imbalances and asymmetries exist even with just one kind of meal, and they would be even more prevalent in a more-realistic scenario where multiple kinds of meals have different demands on your supply of clean stuff.

For example, 10 bowls, 10 spoons, 10 forks. If the make are fork-using salads and spoon-using soups, the shared resource--bowls--will run out before anything else does.
