Is it wrong to “pull rank” as a GM?

A bit of context, I have been friends with everyone at my table for very long. We are chill, and we communicate our issues with each other like adults.

I am the Default GM at our table. Occasionally, someone else might volunteer to take the seat for a oneshot or mini campaign, but if I don’t set up a session, we might spend 2-3 months without meeting. Though we started by playing D&D, over the years I have moved away from the system, tried out a few others, and eventually settled in one that allowed me to tell the stories I wanted to.

About half of the table still really likes D&D, and though I used to sprinkle one here and there, but after they recently asked for one I finally decided to say “look, if you manage to get someone to run D&D for that day, I’ll give them the slot, but I am not.” Of course, nobody wanted to run anything on short notice, and they mentioned that they are a bit burned out from my campaign, so the session got effectively cancelled.

I know I can run/not run whatever I want, but I don’t want to unilaterally kill our regular hangouts (I have little trust of one of them running D&D regularly) so I’m mostly wondering if there was any alternatives I’m missing, or if I was wrong to give an ultimatum like that.
