In this way entropy is not much different from energy. The latter also depends on the model as much as on the physical system itself.
I'm going to disagree with you here. Not that energy doesn't depend on our models. It just depends on them in a very different way. The entropy of a physical system is the Shannon entropy of its distribution of 'microstates'. But there is no distribution of microstates 'out there'. It's a construction that purely exists in our models. Whereas energy does exist 'out there'. It's true that no absolute value can be given for energy and that it's relative, but in a way energy is far more 'real' than entropy.
