@tomr,

No they aren't. I can type 10 and I can type 01, if I state that I will type one of the above pair in my next post, you cannot successfully state which one that will be, no matter how many forces you detect. Because if you state which one I will type, I will type the other. Nobody seriously doubts that I can do this, so there are no detectable forces which will prevent me doing so.
tomr wrote:2) What possible demonstration could you perform to show to others that free will exists.
1) define free will
2) define three essential principles of science
3) demonstrate at least two actions
4) from the above construct an option set
5) define choice and conscious choice
6) demonstrate a choice
7) enact the choice.

You're mistaken, not only do such arguments exist but I'm pretty much certain that I've posted one on this site.
tomr wrote:4) The only conceivable means of making a choice is by a relationship that is determined from initial causes.
Nonsense. If the world is not determined then any phenomenon can be tied to a choice so that it is not determined by initial conditions. You are either begging the question or proposing a trivial notion of pseudo-determinism.

1) you, like every other healthy human adult, unavoidably assume the reality of free will.
2) you don't understand how gravity works, or what it is, do you hold that to be a reason not to assume the existence of gravity?
3) before there was a theory of nuclear fusion there was no understanding of the working of the sun, do you think the existence of the sun was in doubt before an explanatory theory was created?
Whether a phenomenon has been explained, will be or even can be explained is irrelevant to whether or not it exists. Obviously phenomena precede explanations, not the other way around.
You appear to be engaging in special pleading to doubt or deny the reality of free will. As you yourself unavoidably assume the reality of free will and successfully and consistently act on that assumption hundreds of times a day, your stance is irrational.
