Interesting that almost all comments here are completely dismissive of the meaning of staff+ titles, to the point of not even discussing the content of the articles.

Yes, it's true that your title is not your role, and your role is not your job, and your job is not your professional identity. But your title is part of your professional identity, and it's the best shorthand to communicate your status with future employers, or even just with a colleague in a distant branch of your company.

Our profession is young, so it's still in the early phases of defining itself. I'm sure other professions have title bloat too. You still need to play the game, even if you don't like the rules.
