Well that's the whole point of the exercise. To show how even creating a simple thing like a pencil requires vast amounts of knowledge and expertise that cannot be acquired by a single individual. The way I like to frame this is by telling people to imagine they are strapped on an island with no clothes or tools. Let's assume there is fresh water and access to food (some fruits here and there and a decent amount of animals to hunt). Even if you have good knowledge about how our current world and economy works it would still be really challenging to create/build anything that has even a small degree of complexity. Let's say you believe using some metal would help you build some useful tools and you want to start mining for metal. How would you to it with your bare hands? You need tools for that, but what tools can you build with your bare hands? Even cutting down a tree to make something out of it would be really challenging. What would you use, a rock? Imagine cutting a tree using a rock. With no tools it's almost impossible to do anything. But this is the story of humanity, we started naked and without tools, and also with no knowledge about the world, we didn't know that we can make fire, nor how we could use it, we didn't know what to eat and what not to eat. We didn't know why we get sick or what a diseases is. We didn't know where we come from nor where we are heading and yet somehow, afters many years we now build rockets that go to space, algorithms that know what we want before we do, surgeries that make the blind see, devices that make the deaf hear and so much more. These humans are truly amazing.
