This is really about your desire to justify an unjustifiable concept - infinite moral liability for finite beings - despite your guesses about me “being upset over a loss of control”.
Alright, I’ve had my tea, so I’m feeling a bit more charitable.
Your grounding is based on the idea that the root causality is encompassed in the self, and that therefore the self ‘owns’ the results. But the causality passes from outside, through the subcomponents, and then back out again, with the self riding on top in a sense. The subcomponents can radically alter the total outcome, while the self remains riding on top.
You haven’t established why this ownership should not be subsurface. After all, you said it was about causality. You say “but the self is also a whole”, but causally, so is an aircraft, so that doesn’t really help. There are of course many practical reasons, but for your purposes that doesn’t really help, either.
Since I’m weighting on experience, rather than control, I don’t need to establish a perfect sovereign will that re-roots causality locally from the universal level to the individual.
