This is not a definition of economic growth, this is a description of how economists derive an indicator to measure it. It’s like saying that space is defined because you can define hot to get a meter
Parent is right, when you add subjective considerations to what growth is the answer is not obviously “yes”. Or rather, it still is because eventually the universe will be devoid of subjective experience, but that’s a later point and higher bar than the physical limits of our current ecosystem
