The ridiculous notion is thinking growth means using more stuff rather than using stuff better.
A smartphone replaced a camera, GPS, calculator, flashlight, map, stereo, encyclopedia, mailbox, newspaper, and dozens of other physical products while using fewer resources than all of them combined.
That's economic growth: more value, not necessarily more matter.
Meanwhile, the same people who say, "You can't have infinite growth on a finite planet," are often the first to insist that life is unbearable unless they're given more housing, more healthcare, more education, more energy, more food, more subsidies, more services, more benefits, and more spending.
Apparently scarcity only exists when someone else is producing.
