If anything, your point makes the joke funnier - he's managed to make the sentence longer than has to be, in addition to grammatically incorrect, to express the same idea.
Let's make yet another analogy with the body: "Why spend time in the gym working with barbells and dumbbells to achieve a shape and tone that would make you look like a Bronze of Riace instead of doing "just" 10k steps a day?"
Perhaps a dress can be too flowery or stiff; appropriate for a wedding, inappropriate for a day in the woods. A body may be too muscular for a marathon, not enough for a bodybuilding competition.
It is a matter of taste, of situation. Terse writing may fit here and not there; flowery writing may work here and not there. Prescription always depend on the context and the goals.
I agree with you.The point of language is to get an idea from my head into your head with as little loss-of-signal as possible. That is much more challenging than it might sound. Note: an idea might be an emotion.
If I were to write that as simply as possible, I might say: "Yes. Talk is communication. That is hard", or even more simply "Talk hard!!!"
Too much simplification is reductionist, and something is lost. Excessive verboseness is too high a noise-to-signal ratio, and something is lost. There is a balance to be had, and that balance is a moving target, depending on the complexity and importance of the idea and your audience. If I'm trying to convey deep-technical knowledge to a fellow engineer, then I'll be precise and "jargony" - it won't be "simple"; if I'm trying to show that I'm having a good time to my inlaws with whom I don't share a common verbal language, then a beaming smile may be all that's needed.
