My point? That credentials are separate from the license and aren't part of the same thing. That's why many professions don't have licensing. They serve completely different purposes.
I did look up the definitions and they don't support your argument
License: a permit from an authority to own or use something, do a particular thing, or carry on a trade
Credential: a qualification, achievement, personal quality, or aspect of a person's background, typically when used to indicate that they are suitable for something.
Sure, you can characterize the license as an achievement. But it's really just a license.
