If free will did not exist, how would you ever be able to imagine such a thing?

An entity that is constrained by determinism, say a computer program, has no room to "step outside" its own frame and imagine things running an different way.

In essence, free will and consciousness the same thing.

We can imagine tons of things that don't exist. For instance I'm currently imagining a bouncy ball that instead of bouncing according to deterministic laws, bounces according to a mystic will-based system.
