There's lots of ways that licenses can be objectively wrong. They can contain content that renders them invalid, or wording that legally means something different from what the author intended. A lawyer has the "right" to point out such flaws, and refusing to consult a lawyer won't make those flaws go away.

You are of course right about copyright holders being able to chose whether to enforce their license (at least if they were smart enough to use a license that will actually stand up in court!)
