I know all that stuff, I was just caricaturing the person's response because I felt it was a bit glib.
I definitely do not believe we have free will in the most traditional sense, but I am a sort of compatibilist: its clear we cannot make a different choice in identical circumstances for meaningful reasons, but identical circumstances never occur anyway. A person's psychology is a sort of accumulation of all their experiences into biases for future behavior and our "will" is really just a manifestation of those experiences. But to whatever extent we can curate those experiences to produce a long term psychology that we like, I think we should do it.
