Remember the original scenario was "a child telling their parent to walk", so literally using language to communicate a high-level goal to a "lower-level" system. I don't have kids so I have no direct experience with this, but I'm pretty sure that parent's don't actually instruct their kids how to walk. Kids figure it out mostly on their own. Parents might accelerate the process by giving guidance and encouragement, but even that probably is just another feedback channel. The heavy lifting is all in the kid's brain. Contrast that with learning how to play chess. The latter is something that a higher level system really can teach to a lower-level one. Really good chess players eventually develop sub-conscious pattern-matching abilities that are very much like a motor skill, but before that happens a person first has to learn to play chess using slower deliberative methods, and they learn that through language. Other good examples are learning to drive, or fly an airplane, write code. But walking really is different. There's a reason that walking is not taught in preschool. (Physiotherapy is different. And as you yourself point out, some people figure that out on their own too.)
