Your point is not particularly convincing.
Why not?

But your bulleted list is an incorrect entailment of what "a function at its core" means wrt OP, Elm, or Bernhardt's talk, so it seems more like you're reacting to your own reductio of what that quote could entail.
You haven't explained what is wrong with using a pure function to model state changes in an application. To do so, I think you'd also have to contend with the fact that a solution like Elm works quite well in practice.
Here is a quote from the article:
Fundamentally an application can be written to have at it’s core, a single, stateless pure function, behold!
And my point is that, yes, you can do that, but you shouldn't.
