For analytical purposes, the demarcation between production and consumption may depend in part on the level of detail we wish to include. For example, we could have designated "protection from the tiger and the elements" as the consumers' good at the end of Crusoe's structure of production. The tree house would then have been classified as a capital good, which might combine with labor (climbing the tree) and land (the tree trunk) to produce the final consumers' good. For our present purpose of grasping the basic praxeological concepts, however, we can disregard this relatively minor additional step.
