That was one of my initial complaints ...

... and that's essentially what I had proposed for that paragraph.

And yes, since that's written in the overview of Section 2, which
lays out the skeleton of the remainder of the section, the immediate
consequence of this change should be to drop sections 2.2 and 2.3
as well, as explained in my original review.
(To recall: The argument presented there was that, after dropping
inappropriate text, the remaining text in 2.2 & 2.3 would be a
simple -- yet verbose -- restatement of the first paragraph of
Section 2, and hence redundant anyway.)

Bingo!  We are converging.  Thanks.
