Seems to be the same mashup of determinism and bad definitions.
Free will isn't the freedom to determine your microstate, independent of physics. Positing that is incoherent. It has to be something like presence in a feedback loop with measurements.
I pick up cup and drink water because I'm thirsty.
What value is there in retorting: No, trillions of cells maintain homeostasis by triggering a cascade of signals which transferred by neurons and measured by circuits in the brain which creates the conscious experience of thirst and having been trained since birth to associate water with alleviating this negative experience you ingest water. There was no choice only physics and training correlations.
This is only true in the most boring way. To claim: choices don't exist, only physics.
