I think you are missing the point of the article, as that is pretty much
exactly the type of situation where it recommends lists be used.

Actually, your negative abstract turns out to be for a quite positive article. List are like iterators, that's the essence, and as long as you are iterating, it's fine to use []. The prominence of singly linked lists in Haskell has tought me to write my data processing programs in a streaming style.
*Yes.* I've been teaching not just "data processing" - after all almost everything we program is "data processing", no?... but such concrete stuff as physics simulation (diff. eqs.), some other numerics (asymptotic expansions, etc.) signal processing (including sound generation), and I liked to present several examples in a *dataflow style* with plenty of co-recursive contraptions. Haskell lazy lists were natural, concise, and easy to manipulate. We enjoyed it, wrong or not.
Nothing is perfect, not only mister Nobody; calling ANY approach to programming "wrong" is sectarian. A professional coder working on a concrete project may say bad words about anything he wishes, but for a teacher this is a pedagogical sin, and inefficient programs can be more inspiring than some "correct" doctrines.
