As a thought exercise let's stipulate it's possible to model political economies over time and run experiments on them. This would be a pre-condition for identifying "laws" and demonstrating their effects. Such a model would be more complex and require more inputs than weather modeling. We can't reliably forecast weather for more than a few days. It's implausible that you can do anything even close for human history. It's possible to draw robust conclusions about human behavior. But you have to use other approaches and frame the problem differently from "discovering laws of history."
