This completely ignores that you have choice.

You can go get another beer, as would be expected given you had three previously and chose to come to a bar, or you can choose to go home and sleep, or get in your car and drive, or swear off drinking forever.

The fact that options are present to you because of your previous choices (causality) is irrelevant to the fact that you still have full control over what option you select (free will).

Yes, but to speak in video games term, you can still move the arrow of your character. Of course your decision are the product of your previous experience + a lot of other factors. But I believe there is a random factor, when we make a decision, we do choose one over the other.

We'll never know anyway, but I feel like there would be nothing, no universe, no life, no space etc... if there was not this "random" thing.
