I am not sure about the down votes (no reason for them in my opinion) but the casual jab at capitalism looks gratuitous and does not help making the argument seem stronger.
Except a. it’s not casual, it’s part of a thought through argument (which you can disagree with), and b. you fail to explain why he is wrong.
It's not gratuitous if it is central to the argument. The state of affairs they describe is dependent on a virtualized capitalist economy being in place.
