You'd be right, if all value production was in utilitarian, physical stuff. Increasingly however we're spending a smaller percentage of our income on stuff, and more on services and immaterial goods.

To produce a two ton truck, you need to use more than two tons of resource, that much is obvious. But how many resources go into the production of my copy of GTAV? Or my blue-ray of The Lord of the Rings? Or my viewing of a show on Netflix? The marginal resource usage is pretty much nil, just some electricity, paper of plastic. The resources expended in producing the work itself can be significant, but they are amortized among the many millions of copies.

Now obviously there are limits. Humans need physical stuff to survive, that's not going to change any time soon. There's a limit on the amount of actual stuff we can make. But there's no clear limit on the value of that stuff. We keep finding new ways to make little pieces of plastic or bunches of electrons in wires valuable all the time.
