Regarding the nobel prize quote above, while it provides some food for thought, I’m not sure what point exactly it is intended to make.

It's about the process, not the talent. When you've carefully thought through and refined an idea to understand whether it makes sense yourself, that usually provides a lot of guidance on how you can express the idea eloquently to others. You know the questions they'll have and the answers they'll find satisfying, because you already went through the same process. When you're just tossing out your first half-baked impression, it's a lot harder to communicate it well, although some people do have the orthogonal talent of making it up on the fly.
About the nobel price quote: it shows that the most powerful language is unexpected, breaks the obviousness of things, something that ancient greeks knew very well: https://en.wikipedia.org/wiki/Rhetoric
About the nobel prize quote, it isn’t that powerful to me because I don’t really know what it wants to say, and it didn’t lead me to any notable insight either. But maybe that’s just me.
The gap is typically that if something is written poorly we can infer the underlying thinking that went into it wasn't well enough conceived to put out high quality text. You can understand this implicitly when you think about how you would write about a topic that you barely know about vs a topic that you are so comfortable with that the writing doesn't even seem like an effort. Ironically people often don't write about the stuff they know best because they presume it's obvious - and it is, to them. And then they write about the stuff they're trying to figure out - which is poorly understood and poorly expressed.
My answer would be: "eloquence" may be a too-strong requirement, but if you can't express your ideas at least clearly, how can you be sure that they are the right ideas? Because without a detailed description that another human being can understand, this is really hard to judge. Maybe there is a lot of overlooked flaws in your flow.
I have a suspicion that there is a subset of geniuses who just intuitively "grok" some important ideas without being able to describe them to other people. Some of the autistic savants come to mind. But I am not sure if they can be induced to actually cooperate efficiently with the rest of humanity. Whatever happens in their minds, seems to be locked there.
