I'm always suspicious when somebody declares what 'reality' is, so you'll have to have patience with me. You are making the human predicament sound like a snooker ball being hit by a cue over which it has no influence. Who is to say that we have no influence over start conditions? Why can't we choose to modify the start conditions, if not of ourselves, of others around us?
Imagine a newly fertilised embryo. It has, in the genetic combination it has inherited, certain predispositions - it has inherited those, it has no control over them.
Even within the womb it is exposed to sensations at various stages, and to hormones and nutrients of various levels which make subtle adjustments to its growth, it has no control over those either.
As the brain starts to develop, it starts to register input from the budding sensory organs, and it has no control over those inputs which begin to trigger brain development.
That partial development determines how the brain processes the next set of inputs, which updates the brain before the next set, and so on, and so on. We are the sum of those experiences updating the brain's architecture, that sense of 'we' is a subjective experience of that brain doing that processing.
When we think we're in control we're a feedback loop in that brain, and even that feedback loop shapes the architecture for the next iteration.
Who is to say we have no control - it's the fact that there's no mechanism by which something else can get in to the process. Even if it could, what would it do? It would either be some other mechanism that's dependent upon start conditions updated by experience, and therefore no different to that deterministic brain, or it would have some randomness in it - which would be free, but not will.
