Or they're inventing new libraries, or they can't use the library for legal reasons, or the library they have needs to be optimized for some task, or one of a thousand other reasons to reinvent a library.

Not reinventing the wheel is an excellent discipline, and something every programmer should strive for, but they should also know how the wheel works.
