OK, but let's say that value isn't related in any fixed way to material or energy inputs. It's based only on market forces. In that case, why is exponential growth in value not possible?

What exactly is it that you're "valuing" here?

What's it tied to?

How does it grow without some real, resource-based, basis?

What evidence do you have for such a thing existing?

How about evidence that it cannot? What would falsify your premise?
