You don't have to put stress on any words on that sentence in English, and it will be sound perfectly fine. The vast majority of sentences don't stress particular words.
You can also add implications by the gestures you make in between words. That doesn't make English complicated, that's just an irrelevant thing you can do.
Calling such a thing 'hugely important' is just wrong. I didn't miss the point, I think the point has no connection with actual speech.
