Yeah, looks like I conflated a lack of freewill with a determined universe.

But even with the quirkiness of quarks, there is no obvious place to rest the claim that we exert agency over our decisions.

And even then, I think I may have layered the explicit reference to freewill onto this idea unnecessarily. The key point is that the causal regression is functionally infinite. Picking a starting point is prone to being influenced by bias, and even when there is no bias, the starting point itself will bias the following narrative.
