How does it avoid determinism? Or physicalism? To me this doesn't make sense. The concise version of the regress argument you state as:
More concisely, free will requires ultimate self-origination, which is impossible
Admittedly, no one has absolute free will. There are always influences and even subconscious actions that don't require a conscious choice. However, I hear you taking an extreme view that free will of any sort is impossible, that you cannot contribute adequately to any change that occurs sufficiently to be responsible for what happened. Basically, I hear you saying that you cannot make a choice of any sort and be responsible for that choice.

Are you responsible for the act of changing your mind should it happen to occur? If you are not responsible, who or what is responsible for that occurring? I could suggest "evolution" or "natural selection" or "random neurons firing" as pseudo-agents whom some might see as responsible. They are pseudo-agents because they do not actually make choices themselves.

I wonder what is required to have a "rational thought process". Do we need to make a choice in the process, for example, to remain rational since we don't have to? Do we have adequate free will to make that choice?

If free will is impossible, how could you live your life in any other way than you find yourself living it?
It's an interesting topic. Thanks for bringing it up. I don't know the answers. I'm more trying to clarify what is involved for myself.
