No, there are other reasons to think it's false. For example, if individual choice is the driving principle of the world, where did we come from? In your framework, existence itself is equivalent to slavery because we didn't choose it, and suicide is the only form of emancipation. Therefore, as long as you live, you contradict your own ideology.

Ultimate individualism is neither coherent nor good. A creator God, however, is both. He is logically necessary, and has revealed himself in history. So I choose to believe his word, and approach human flourishing in the way he has designed it.
