I guess I must have been replying to the wrong type of person on a proprietary social network, because it decided I wanted to see a post from some right-winger.
It was quoting "My Dinner With Andre" and it wasn't referring to 15-minute cities specifically, but the context in which the quote was used made me think this quote gets at the core of the fear some people have for what they think the 15-minute city stands for.
Longer quote here, but I'll shorten it:
