Yes, and I went one step further, specifying the "N-good" protocol, which characterizes objects based on the (log) of the number of components. Raw material is a 0-good. Something with 10 components is a 1-good. Something with 10000 components is a 4-good, and so on. An aircraft carrier is an 8- or 9-good. Of course there is some ambiguity around what constitutes a component - perhaps a better way would be to count the number of distinct operations required to produce the final product, recursively. But I think just counting the parts is probably okay for most things.
