OP here:

Universities are not trade schools, they are often focused on education for the sake of pursuing knowledge, not how to train you for everything you need in your career.

Computer science is not software engineering; think of the difference between physics and mechanical engineering.

A lot of computer science classes are highly theoretical and have only tangential relationship to what it takes to write a commercially successful program.

BTW: This is the similar for doctors, in the US, your doctor has to get a license in addition to a degree, and the license requires self-study in topics that aren't covered in medical school.

While I think that ought to be a requirement for getting a CS degree, not all universities do. Moreover, being able to code isn't a boolean - while some people are indeed totally incompetent, among the competent people, some are better than others, and some have strengths and weaknesses that would make them more ore less suited to a particular role. It behooves an employer to try to measure these things.

Computer science doesn’t teach you how to write code.

Not in my experience.

... No.
