Prof DM comes from a different school. He likes simplicity; he only cares about what goes on at the table. It's a storytelling exercise to him, not a simulation.
But whenever I simplify like this... I get bored and lose interest. It's no longer real to me, or interesting. The world becomes flat and arbitrary. I don't want to be a "frustrated novelist" trying to see my players through a storyline, or dropping sequences of interactive scenes in front of them. I want to be the demiurge of an interactive world that grows, evolves and behaves separately from the PCs, but which they can influence and build on as well. (Similarly, I've never liked PLAYING RPGs - that is, being a player, not a DM. I can barely get through an entire session without growing bored, unless I know the DM is from the same "school" as me, and is trying just as hard to simulate his world. To this day, I've only played with one other DM like this, and that was over two decades ago now.)
I'd read about old school campaigns and West Marches games with numerous, proactive players, and thought that was the kind of game I wanted to have. Maybe one that would grow so big that I would have sub-DMs. I'd love to have parties competing with each other and scheming against each other; building kingdoms and fighting wars. I've dreamed of this since I was a boy, sitting on my grandmother's couch reading the Rules Cyclopedia 30 years ago, and building castles and rolling kingdom events in my notebooks.
I've always wanted to take the game "to the next level".
But now I'm 42, and after more than a quarter century of DMing (admittedly with a hiatus from 2005 to 2019), I just don't think that's ever going to be possible. It doesn't seem to be what the hobby has become or wants to be.
