I'm confused by the "because" in the first sentence and the "so" in the penultimate. I see no reason why the one thing should cause the other. As I say, it's logically possibly that there could be such a causal relation, but in general there's no reason to think that doing X should feel like doing Y -- you'd expect it to feel like doing X! If I don't know what my choice will be, I'd expect that to feel like not knowing what my choice will be. Which is a distinct state from feeling that I have freedom of choice.

In fact if you use your imagination, you can come up with scenarios in which you don't know what your future choice will be, but it clearly doesn't feel like a free choice. E.g. if you say "I will choose to get a coffee if I roll the die and the number is 3 or above, or a tea otherwise."
