You've conflated feelings with facts and, in that sense, have mischaracterized my objection. It is most certainly true that there can be no actual meaning to any part of reality in a determined universe. So you can declare all of the universe to be determined and "choose" (sic) to feel like there is meaning anyway but that would not be the same as the universe or any life within it actually possessing meaning. On your view, it cannot. So in a determined universe everything you have written ends up being an absurdity. Persuasion, moral responsibility, using words like "should" and "ought" or "deserved" or "earned" are bereft of any meaning. All things just ARE, all the time and they could not be any other way.

As Nancy Pearcy has written,

“Adherents of scientific naturalism freely acknowledge that in ordinary life they have to switch to a different paradigm. That ought to tell them something. After all, the purpose of a worldview is to explain the world—and if it fails to explain some part of the world, then there’s something wrong with that worldview. …
Since their metaphysical beliefs do not fit the world, their lives will be more or less inconsistent with those beliefs. Living in the real world requires them to function in ways that are not supported by their worldview…

The things that matter most in life, that are necessary for a humane society -- ideals like moral freedom, human dignity, even loving our own children -- have been reduced to nothing but useful fictions. They are tossed into the upper story, which becomes a convenient dumping ground for anything that a materialist paradigm cannot explain.”

Being a materialist, I can understand why you might believe that it has been discovered that we are not free in any sense but the latest science says otherwise. The info-theoretic/digital physics interpretation which has emerged as a result of decades of experiments in quantum mechanics specifically contradicts physical realism and locality (eg. http://arxiv.org/abs/1508.05949 ). An experiment from Anton Zeilinger et all in 2012:

"No naive realistic picture is compatible with our results because whether a quantum could be seen as showing particle- or wave-like behavior would depend on a causally disconnected choice. It is therefore suggestive to abandon such pictures altogether." ( http://arxiv.org/abs/1206.6578 )

And, given everything we know of quantum gravity, spacetime is emergent from information and physical reality is holographic in nature. See people like Seth Lloyd, Fotini Markopoulou, Ed Fredkin, Herman and Erik Verlinde, and Leonard Susskind to name a few. They represent the consensus position and all quantum gravity research to speak of currently is going into emergent spacetime, where spacetime emerges from patterns of entangled quantum information.
Which is all to say that materialism has been falsified - by physicists - and so has deterministic causality.

Since my interests tend more toward philosophy, however, I find the Introspective Argument alone sufficient to reject materialism ( http://blog.proof.directory/2014/05/25/introspective-argument/ ) while the science is supportive.
