I would prefer to tie Elroch down into rephrasing it in English. The philosophy paradigm needs to be preferred to that of physics if the physics one is so incomprehensible. An intelligent person shouldn't have to struggle to understand this, because it isn't as if it's too intellectually challenging. It just isn't stated in a meaningfully comprehensible way.
I accept the difficulty of communicating about this. I have tried to strip it down to fundamentals and am guilty of thinking out load.
But if you think my musings are opaque try reading this sort of stuff!

elroch:"Causality means that a free choice can only affect what happens in its future light cone"
sounds a lot like an attempt at damage control, as you repeatedly stated that you dont even believe in free choices. i may read the rest later..
It's clearer to ignore the first half of that post. The "freedom" there means that the choices come from outside of the system, so they are free with regard to the system.
The formulation in terms of information seems a lot clearer to me.
