(1) as such? Meaning that there is some metaphorical context here of which I've been unaware? Or is this some indication that "physical body" needs airquotes or something? I have no idea what this phrase means in this context.
You are just using the wrong metaphysical model, I think.
It seems to be talking about the mechanistic biological body, which actually does express itself as such, so they actually got this one right.
That's actually problem with things like cancer, too.
It expresses itself quite well.
