Well, it's a good definition. The primary problem is that you've defined the
term in such a way as to be unknowable. I.e., it's a definition that
prevents you from determining the answer to any of the questions you might
ask about it.
Unfortunately, I think most definitions of "free choice" where you might ask
"do we have it" are going to either be by definition unanswerable or by
definition trivial. If you define "free choice" as "how humans make
choices", then yes, obviously we have it and nothing else does. If you
define "free choice" as "able to do anything conceivable" then obviously we
don't have that, or we'd be flapping our arms to fly to the moon.
Another possible definition would be "a selection made by a system from one
of multiple behaviors, where the selection of behavior is based on existing
circumstances, and the selection of which behavior before the selection is
made is impossible to predict by any system including the system making the
selection." I.e., it's free will if it's impossible to know what you're
going to pick before you pick it, even for you. At that point, does it
matter whether it's natural or supernatural?
In that definition, yes, we almost undoubtedly have free will, unless we're
all Sims or something, and there's someone "outside" who can predict what
we'll do by examining the state of the universe.

Sure. But you see what you're doing? You're defining "free choice" as
something supernatural, then saying "if there's nothing supernatural,
there's no free choice." You have basically trivialized your conclusion by
presupposing the mechanism by which free choice comes about, then asked what
happens if that mechanism isn't the basis of free choice.
I'd prefer to approach the subject by saying "Of course we have free choice.
It's unprovable, but we also know we have self-awareness, which can't be
proven to anyone else. But what is this free will that we have?" I.e., I
prefer to approach the topic by defining free will in a way that doesn't
address the mechanism, then ask if there are mechanisms that would cause
that to come about.

That's like saying I didn't choose to make a fist, because that's just
muscles contracting from electrical signals from my brain. You're mixing
levels here. You're looking at choice as something that happens at the
atomic level, and it's (probably) caused by some higher-level combination of
things. ("Probably" in the sense that maybe it is supernatural after all.)
I.e., something without self-awareness can't make a choice, right? Yet no
atoms of your brain "think". No neuron of your brain "thinks." It's the sum
total of the neurons in your brain which "think." To say "I can't think
because none of my atoms think" is like saying "I can't make a choice
because all of my atoms are deterministic."
I.e., "choice" is a pattern of thought, not a fundamental property of the
universe. You *know* you're making choices. You're looking for the mechanism
whereby those choice are made. You're defining that mechanism as something
supernatural, then asking "if there's nothing supernatural about it, why
does it feel like I'm making choices?" If you weren't making choices, you
wouldn't be asking the question in the first place. Nobody asks "Is doing
bluflert a result of determinism or randomness" because nobody is doing
bluflert.

It was an analogy. We *are* talking about definitions. :-)
A rock doesn't exist anyway. It's just a bunch of individual atoms
interacting. We just *call* it a rock. The concept of "rock" is in your
head, not out there. :-)

It's a sentient independent being, *and* an object. (Not inanimate,
technically, because that word means "doesn't move", but I know what you mean.)
No, humans are animate sentient independent beings made out of inanimate
objects.
(Oh, and it's not the human "mind" as such, but the human brain, that's just
an object. I expect the human "mind" is the pattern encoded in the brain.
Still subject to the same physics, but in a different way than the rock is.
For example, the human mind can completely disappear without a trace, while
the brain or the rock cannot.)
> If it happened as a consequence, it's not a choice.
By your definition, *perhaps*. I think it's possible to have free will *and*
be deterministic, because I don't equate free will with the supernatural. I
equate it with a type of processing that goes on inside sufficiently
intelligent minds.
Is it possible to be deterministic and intelligent? If so, what part of
intelligence is involved in free choice?
Is it possible to be self-aware and deterministic? Is there any reason to
believe you can't be self-aware and deterministic? That it would be
impossible to (say) write a computer program that would learn enough to
eventually understand its own workings and understand itself, becoming
self-aware?
[ I recently wrote a long screed on the question of "what is consciousness"
which I'll likely have a chance to organize later this week. It'll be fun
incorporating some of this stuff too. Then I'll let y'all rip up my
assumptions and bad logic here. ;-]
