Most wealth is material, but that doesn't mean you need ever more material for ever more wealth. The obvious common example is electronics. Shrink a computer or smartphone to use half the materials while otherwise maintaining the same capabilities, and you've increased the amount of wealth it represents.
Raw materials aren't worth much. We mostly pay for the arrangement of matter, not the matter itself. A person who owns a few dozen tons of lumber and plastic and metal is not equally wealthy to a person who owns a house of similar mass. The average human today is far better off than a few centuries ago, not because the average human has more material, but because they have access to material that's better arranged.
Population growth is one thing that needs to be limited. People need space. But there's no inherent requirement for economic growth to be the same. We "just" need to grow through more efficient use of natural resources rather than through greater use.
You bring up many good points, but I don’t think you need to accept the main point of the original post:
>Most wealth is material...
The wealth/value of the companies that control the intellectual property that the world relies on, are at least as valuable as the companies that control the materials we rely on. Microsoft was maybe the first company to grow huge that didn’t rely on control of oil/railroads/etc for its wealth and there are plenty others. I don’t see that trend reversing - as you said we mostly pay for the arrangement of matter, not the matter itself.
