You do, because there was a single creative force that created the universe and that is apart from the universe.
If I choose my choices, that is infinity regress.
This creative force has split his personality into billions of people and this creative force (God) chooses whatever he wants to and is above the laws of physics.
If anyone chooses his choices, that is infinity regress.
Your brain which could be referred to as the radio can impact randomness
This is circular reasoning. You say that randomness makes choices, but that choices make randomness. Thus, there is still no choice, because the circle isnt chosen.
as shown in double slit experiments. So the creative force using the brain as a radio has free will and it is expressed on the quantum level which impacts the atomic level and has a cascading effect.
This is talking about results of if free will existed, not if free will exists.
You could also see platos cave for a theory that can help explain how free will escapes the cause oriented universe
Sadly, it cannot escape anything.
There are only 3 options we know of:
1. Randomness or out of nothing
Randomness is not a choice, since randomness is by definition not chosen. Not chosen is not a choice.
Out of nothing is not a choice either, since one cannot choose what comes out of nothing. If one cannot choose, its not a choice.
2. Having a cause
Cause of choice isnt chosen. Cause of choice isnt a choice. What isnt choice isnt chosen.
3. Being circular, choice causes itself.
This is like saying that cause of choice is a choice, or that "A causes A".
It is divided on two options:
Every choice being a choice of another choice, thus infinity regress.
Or
Just one choice, caused by itself.
Neither of these are choices, since even if choice causes choice or causes itself, you still cannot choose which choice is caused by itself. If you cannot choose which choice is caused by itself, then neither of those two options are choices.
To make it simple, no circle of logic you can come up with can be a choice, as every circle of logic exists independent of choice. Existing independent of choice cannot be a choice.
Not even future choice affecting past solves this, because future choice isnt chosen. What isnt chosen cannot solve this.
