The second law is an empirical statement. This entanglement based approach is an attempt to understand the underlying physical mechanism that controls the spread of entropy. If this picture is right, the next question is what is the physical process behind entanglement.

The second law was proven as a statistical outcome. Ordered states are vastly outnumbered by disordered ones.

And isn't the whole description of entanglement based on empirical observations anyway?
