I have to say that I don’t really think your argument shows a lack of free will. I mean, so what if we all go to work, come home, watch TV, and go to bed? We get to choose what sort of work we want to do. We get to choose to some degree where we live. I don’t watch TV, so there’s that, but even if you do, you have a million channels to choose from. You get to decide when you go to bed. I mean, these may all seem like relatively minor kinds of freedom, but we have all these choices, both in the long term and in the short term.
So I still think we have free will. Sure, there are broad strokes in our lives that are similar, but we get to make plenty of choices. We don’t all get married. We don’t all have the same number of kids. We don’t all make the same choices in terms of how much we want to material things. We have choices in the big stuff and the little stuff.
