I think you're misunderstanding slightly the utility function of the logical device here. It's not so much that we cannot analyze a complex system using this criterion, it's moreso a tool that allows us to identify a logically tenable pathway for investigating a specific element of reality. For example, a poster above noted that I was misapplying the razor because he went one level below where I was analyzing. He's not necessarily incorrect, and neither am I. You interrogate reality at multiple levels of magnification, which is why you don't need to know how genes specifically work to know that they work and make predictions based on their prevalence, for example.
