I believe you are correct.

Entropy is not a physical quantity, it is a measure of how far a system is from equilibrium.

Lots of people talk about order/disorder or macro and micro states, not realizing these are things we've invented and aren't physical in nature.

That’s funny because the original thermodynamic entropy is defined only for systems in equilibrium.
