IMO the economy is much more like a biological system than a physical one. Systems that are studied in physics are neat and simple, with components that obey precise laws. Systems that are studied in biology are irreducibly complex, and often the laws that govern them are unknown. First-principles thought experiments can work beautifully in astrophysics, but they're bound to fail in anatomy. So it goes with economics.
