Abstract
In a recent reply to my criticisms (Found. Phys. 55:5, 2025), Carcassi, Oldofredi, and Aidala (COA) admitted that their no-go result for $\psi$-ontic models is based on the implicit assumption that all states are equally distinguishable, but insisted that this assumption is a part of the psi-ontic models defined by Harrigan and Spekkens, thus maintaining their result's validity. In this note, I refute their argument again, emphasizing that the ontological models framework (OMF) does not entail this assumption. I clarify the distinction between ontological distinctness and experimental distinguishability, showing that the latter depends on dynamics absent from OMF, and address COA's broader claims about quantum statistical mechanics and Bohmian mechanics.
