I think the key issue is whether the FAR's organization is chronological or not. I assume there is general agreement that the FAR has structure, but I disagree with the statement that the FAR is structured in the chronological order of the acquisition process. Likewise, OP mentions ethical considerations and it is a reach to say it occurs before conducting acquisition planning, market research, and deciding on an ordering authority.
I've read the OP's article a couple of times and I still don't understand the "so what" of his discussion. It reads like he is trying to provide insight to a new CS. However, if a CS has an A&E requirement is he or she to assume that they do not have to glance at Part 36 until after Market Research or an ordering authority is determined? The CS should be reviewing several of the parts concurrently throughout the acquisition process. Also, OP should have hit a hard stop when he lumped Part 16-41 into a single group. When you have four groups of 5 and one group with 25 --you have to question your original assumption.
