Agree 100%, but reading your post made me realize that perhaps some people who disagree are coming from the position of believing that you shouldn't have to have these skills in order to DM. And that's actually a really interesting question. Should you have to be a good actor in order to be a good DM? Or is it fine that some DMs can pull off humor and deception, and other DMs have to rely on other tools?
If you can't act to some extent, you'll never be as good of a GM as a person who can. If you don't have the spatial skills to make interesting maps, you'll never be as good of a GM as a person who can. If you don't have the tactical skills to play monsters and NPCs to the best of their abilities in combat, you'll never be as good of a GM as a person who can. If you don't have the fortitude to make lots of notes in preparation to play, you'll never be as good of a GM as one who does. If you can't do voice work to some extent, it harms your ability to GM compared to someone who can. If you can't craft a fine dramatic story you'll never be as good of a GM as someone who can. If you can't narrate a compelling visual picture, you'll never be as good of a GM as someone who can.
As a GM, you have to wear a lot of hats. Very few of us are great at all those hats, but your job as a GM is to lean hard into the areas you are good at, while working your best to make up for the deficiencies you may have in other areas.
Sadly, GMing is a skill. Just as with athleticism, we might not all have the capacity to be world class. But that doesn't mean even if we can't be world class, that there isn't value in developing the capacity we do have.
