AB,
So this explanation that undoes me does so by effectively claiming the existence of you or I to be a logical impossibility.
No it doesn’t. It just explains that your concept of “freedom” (neither deterministic nor random) is a logical impossibility.
You appear to be thinking yourself out of existence and being replaced with what you deem to be "a sense of agency".
No, "I" still exist but I also know that as an explanatory model my workaday sense of agency fails. That’s all.
But I know I exist. This is me typing these words.
Yes I know, so do I. What “I” consists of though cannot be your romanticised notion of an indivisible whole – rather it’s a complex biosphere of microbial communities. Here’s a link to get you started:
https://www.astrobio.net/biosphere/the-rare-biosphere-of-the-human-body/ Also the touching of the keyboard is totally irrelevant, because the point is that you make a conscious choice to press a key, and the resulting consequence is that the key gets depressed. The mechanics of how it actually happens is irrelevant and the point you are trying to make is trivial.
No, it’s totally
relevant. The problem here is that you don’t grasp the meaning of the term “analogy”. An analogy is a comparison between
different things for the purpose of making a point. The point here is that the analogy illustrates that your experience
of phenomena cannot be assumed to provide therefore the explanation
for those phenomena. Whether the phenomenon at issue is decision-making or how we pick things up makes no difference to the basic point. This has been explained to you many times already so I don't know why you keep ignoring it.
