Again: freedom from natural law, already stipulated as deterministic, is not involved. Not necessary. Excluded. Nothing supernatural is included. Your assumption of necessarily supernatural freedom is not granted. Meanwhile: being predetermined is irrelevant. The best example here - the simplest illustration I could come up with - is a driver approaching a traffic light. We went over that in great detail. If you missed it, please review the discussion. And so we see that the matter of interest is the process by which all this internal human mental activity is determined, and in turn determines what follows. This is quite close to what might be called "self determination" - something you have considered.
