Frankly, you’re not defining or arguing anything here. You’re simply making unproven assertions which you back up with more unproven assertions.
Essentially, your “argument” is this: There is no free will. Why? Because if there were, you would be able to choose. But since you can’t choose, there is no free will.
I had intended to write more, but decided against it. Whether you believe in free will or not, I will be exercising mine.
