The problem basically being what happens when you marry the logic of commodification (money, oil, grain, etc equally interchangeable) with the growth requirements of a debt-interest based economy. Either we have to make off-world into the new growth industry or financial capitalism will be the end of us.
This has nothing to do with capitalism. Any economic system would face the exact same problem. Growth is not inherently capitalistic, its just the system that can sustain growth while others can't so its running into these problems while others collapsed before getting there.
Its a simply property rights (or externalizes problem) that is universal and incredibly difficult to solve.
If you are interested in this sort of thing, and have already read Debt, the First 5000 Years, learning about gift economies is worth it.
And Graeber's Toward An Anthropological Theory of Value
The False Coin of Our Own Dreams is worth reading for a mechanical account of how gift economies function, and the status of heirlooms and other valuable objects.
