Well, that's how physics works. Physics is stupefyingly strict about its methods. Most sciences don't put quite as much value into models. The problem is that in a desire to strictly follow the method, physicists have become complacent with regards to extraordinary claims. Sure, the universe is full of dark matter, connected by tiny strings, in between folded up dimensions, but gravity is leaking away into parallel universes, since that's what the model predicts (rather than it just being a mathematical anomaly arising from botched assumptions). It's comparable to an economic model that describes inflation as the work of invisible leprechauns who increase prices during the night. Sure, it might make accurate predictions, hell, it might even be true, but you should not put any value into it unless there is evidence that the universe actually works in the extraordinary way the model claims it does. Biology has followed a much better path over the past century, and biologists are rapidly building up an extremely thorough understanding of how biological systems work without relying heavily on algebraic models. Physics fails to provide explanations for even the most basic physical phenomena like motion. It's effectively just assumed to exist as a law because some authoritative physicist said so and all other models rely on it. |

To put it differently, biology can't answer why paraplegics can't walk without first answering how people walk. You can't explain walking if you can't explain motion. Unless the biologists have been holding out on us, they don't have an explanation for motion that would satisfy us any more deeply than you do. Thus, if physicists can't explain something as basic as motion, then biologists can't explain something as simple as why paraplegics can't walk.
