These concerns are already perfectly applicable to the current state of the world, no? More planetary boundaries keep getting crossed due to unnecessarily large resource usage, the poorest people don't have access (even though they could) to the resources necessary to survive...
That's exactly why I'm concerned. It seems to me that we will only exacerbate the problems we have today, not alleviate them. We would need dramatic breakthroughs in energy technologies, but also... I don't know, some means of acquiring raw resources which doesn't strain the planet.
