Economic growth has two components, one material and one non-material. As you correctly point out in your post it is possible to create value without increasing the use of resources. This is what some people call dematerialization of the economy and what I prefer just to call increased resource productivity. This process of dematerialization is driven by technological improvements. But technological improvements have limits. As Herman E. Daly (dean of ecological economics) would say 'We can surely eat less in the food chain, but we cannot end up eating just the receipts'. This means that we can make the material component of economic growth smaller, but it will never become null.

One shouldn't dare make economic points regarding limits to growth without taking into account physical limits and the relationship between economy and fundamental scientific laws as the laws of thermodynamics.

The first limit to growth is the fact that the earth is a finite environment. Once I've said this you may think, well, we can recycle non renewable resources forever. Then I'll ask you to keep your faith in technological improvements at bay and do a little research on the meaning of the Second Law of Thermodynamics. If you after doing this research still believe that this universal scientific laws might not be valid after all, I ask you to search for what Albert Einstein, the scientist who turned human knowledge upside down in the last century, thought about this fundamental laws.

Kind regards
