For the same reason we render images as color and light, instead of displaying a table of hex values.

They both have the same information. They both can be understood.

And both have their uses.

A comment or documentation for a trivial bit of code, is clutter, and a waste.

The denser the code, the greater the value of a comment. And, the larger the code base, the more value there is in documentation. It can be very tedious to discover the implicit structure without one.
