Because there are no robust, debugged standard library functions that have existed for years in C?
When did C add standard library functions for Vecs and HashMaps? You're putting words in his mouth, no one claimed C lacked "robust, debugged standard library functions". It's no secret that the C standard library lacks implementations of a variety of things that programmers use on a daily basis.
