Partially agreed, though, I replace two meals a day with the UK equivalent. I suffer from depression and ADHD, so while I generally collect myself enough to make a proper evening meal, prior to Huel I would often skip or forget meals, and binge on junk later in the day. I'm working on 50/50.

From the horses mouth, most use cases I've heard are pretty sensible. Very few users treat it as their entire diet. You've a good point that food is great, and it's good to do it right. I'd hope students would take the opportunity to learn, but they rarely do. Still, Soylent or equiv >>> pizza. Most other arguments against it/characterisations are a little circular at best, or reduction to absurdity at worst.
