Yes, you can falsify a hypothesis about a model built from operational definitions, but you can't actually know that this model corresponds to reality at a physical level. Science is about knowing reality at a physical level. I can come up with an operational definition for a human soul (psychology means "study of the soul") but I can't actually come up with a scientific experiment that demonstrates that I have one. I don't actually have a problem with unfalsifiability, I think these models are quite valuable, I have a problem with it being presented as scientific truth.
