I think you are referring to Professional Orders (https://en.wikipedia.org/wiki/Professional_order) and, depending on where you live, there may actually be one.
In my country, computer engineers have a professional order they can join after graduation, in the same exact way all the other kinds of engineers they've studied with do. Unlike some other engineering fields, the order does not enforce nor require active membership in any order to work.
There've been a few attempts to get this going. So far none of them have worked (see also: any kind of union specifically for tech workers).
The other professions have a "closed shop" - you cannot work in that profession without joining that association.
e.g. in the Anglosphere, you cannot practice as a lawyer without being a member of the relevant Bar Association, and to join that you must "pass the bar" which is an exam.
If we had this in Dev, then we wouldn't be able to write code for money until/unless we were a member of the Software Dev Association, and they wouldn't accept us until/unless we'd passed a rigorous exam (passing the bar is something that takes years of study) to prove that we could code. Then we wouldn't be facing ridiculous "but can you actually code?" tests during interviews.
But creating that closed shop has always failed (so far). Employers don't want it, and new coders don't want it. It's only us old hands who expect to be grandfathered into it that kinda like the idea.
