You ask how this is impartial.
I’ve already answered that upthread. If you’re not sure where to find it, I’m happy to link it. But I’m not going to repeat it, because that’s not the real issue here, and going over it again would just put us back into the same cycle that led me to write about impartiality in the first place.
What’s become clear to me is that we have a fundamental difference in philosophy when it comes to running tabletop campaigns.

“There is no DM impartiality when the DM is the sole source of all information. It's not possible for the DM to be impartial.”
If you believe that, then no argument I could make will convince you otherwise. Everything you’ve said makes perfect sense working from that assumption.
But my contention is this: a referee can be impartial, even as the sole source of authority. It requires specific techniques and habits, which I’ve outlined earlier in this thread.
This is a crossroads. Either you believe it’s possible for a sole authority to act impartially, or you don’t. And if that foundational point isn’t agreed on, then nothing else we’ve been debating will land, because we’re not even talking about the same thing.
If you're interested in how to maintain impartiality while being the sole authority at the table, I’m happy to share how I do it. But that conversation only works if you’re open to the idea that it can be done.
And if you're not, that’s fine too. Just be upfront about that belief. It'll help avoid frustration, especially when talking with people who do believe impartiality is possible. Because if you treat impartiality as categorically impossible, then every argument built on its possibility becomes irrelevant to you by definition.
Which brings me back to your post. I’m not addressing the specific points you raised, because unless we resolve whether impartiality is possible, nothing else matters, at least not in the discussion we’ve been having.
That said, even if we don’t agree on this point, I still think we have useful things to say to each other. There’s a wide range of techniques, tools, and system elements that work regardless of philosophy. For example, you might find my use of random tables helpful in your games. Or maybe we both have solid subsystems for something like running a formal gathering like a dress ball.
Philosophical disagreement doesn’t mean practical incompatibility.
