"By nature, this system leads to capital accumulation. Since no capital is infinite, accumulation in one place means removing it from somewhere else."
I agree with the first sentence but the second assumes the economy is zero-sum. This is only true to a certain extent within some domains, like ownership of physical land.
Not I don't money is zero zum. But in the end, what you can exchange for it is. The current virtual nature of money has nothing to do with it, it's just yet another mecahnisme to accumulate capital, in the form of the potential of things you can acquire represented by a number. This potential is virtual, and moving, it's a (broken) mecanisme, but the things you can buy with it are not.
