I am saying that encouraging consumption does tend to lead to over-consumption. Equilibriums exist in textbooks, but in the real world there's a clear tendency for oscillation in economic markets. If you're pushing one way, yeah, you're a part of the problem when things go over the line in that direction.
Advertising is nowhere near neutral in its effects on consumption. Sure, it may have some minor effect that reduces consumption, but taken as a whole that's not what it does at all.
Note here this is different from what you're reading into my position. I'm not saying marketing is inherently bad. But I am saying that it does push in a direction, and too far in that direction is bad.
