But GDP isn't a natural resource, it is an artificial number extracted from insanely complex valuation of fiat currency, debt, policy, and subjective worth, all of which are subject to geopolitics and whims. I completely agree that nature eventually puts an end to exponential growth, but I don't see how it puts an end to exponential wealth.
