Claiming that anyone discussing inequality is implying economics is a zero-sum game is making a strawman argument.
There is a continuum between two extremes - at one extreme, you have a zero sum relationship, where the total output (as measured by some sensible metric) is capped and it gets divided up, through to a view where there are unlimited resources and no constraints on growth, and the activities of people are synergistic but not competitive.
Both ends of the continuum are easily shown to be fallacious, but your argument only holds if you assume the unlimited resource end of the continuum is true.
The reality is that there are finite resources, and physical, biological and sociological limits how fast and efficiently they can be sustainably exploited. That said, there is clearly a lot of room for improvement in how efficiently we use resources - as many Internet startups are doing - as well as how sustainably we use them.
