This belongs more in a "pro-free market" thread but couldn't think of any existing ones so decided to add to this one.
Have always loved these as basic examples of the complexity of the invisible hand in action. How it is easily able to peacefully coordinate the actions of millions of individuals across different cultures, languages and countries in ways that give rise to things far beyond the comprehension or capabilities of any single person to ever produce by themselves.
Robert Elickson said:
An alert observer can find in everyday life abundant evidence of the workings of nonhierarchical processes of coordination.

Consider the operation of markets. Every day hundreds of thousands of people assist in supplying the food needed to sustain the seven million residents of New York City. No single individual knows how this aggregate feat is accomplished, and no one goes to work with this aggregate objective in mind. Nevertheless, New Yorkers invariably find food on their market shelves. This happens because a host of people consciously carry out tiny tasks that require them only to be aware of how their particular task meshes with the tasks of their immediate neighbors in the food-supply system. A Kansas wheat-farmer, for example, must know something about how his harvested grain is trucked to the local grain elevator, but he need not know how bread baked from his wheat is trucked from New York bakeries to New York supermarkets.
And the good old "
I, Pencil" by Leonard Read which was summarised into a ~2-minute speech by Milton Friedman:

"...millions of human beings have had a hand in my creation, no one of whom even knows more than a very few of the others.

Here is an astounding fact: Neither the worker in the oil field nor the chemist nor the digger of graphite or clay nor any who mans or makes the ships or trains or trucks nor the one who runs the machine that does the knurling on my bit of metal nor the president of the company performs his singular task because he wants me. Each one wants me less, perhaps, than does a child in the first grade. Indeed, there are some among this vast multitude who never saw a pencil nor would they know how to use one. Their motivation is other than me. Perhaps it is something like this:
Each of these millions sees that he can thus exchange his tiny know-how for the goods and services he needs or wants. I may or may not be among these items."
