Thus it is within possibility that you could discover if the proposition "I will do X on December 15, 2010" is true or false even today on April 15, 2010
Yes it does. But so what? Whether it is true or false depends on what I do. So if it is true, then that means I chose to do X, and if it is false, that means I did not chose to do X. Still don't get your difficulty. Are you supposing that whether I chose to do X or not is somehow preordained (as you wrote earlier)? But why assume that?
As Wittgenstein remarked, it is as if a fly were buzzing around, looking for a way out of the bottle he thought it was trapped in, and all the fly had to do was to look up and see the opening in the bottle. It would be so easy for the fly to look up and see the opening. But he keeps buzzing away, and going round and round. But never looking up.
