When you say "the world we want to have" I think you mean "the world I want to have" since most people seem to want a world where they primarily consume media. I think most people would say that the moral good is optimizing for consuming media, because that is what they want to do.

553,000 people in the US are homeless, but I don't think most would say they "don't want a home". 2.3 million people are in prisons, but I don't think that's the place they "want to live". 15.1 million have an alcohol abuse disorder, but I don't think they would all characterize it as "wanting to drink". 12 million people in the US experience rape, violence, or stalking from a partner every year but I wouldn't characterize them as "wanting to be in that relationship".
Behavior reflects all sorts of things outside of the person's intentions and aspirations. One of the goals of a just society is to give people a framework that helps them reach their goals.
Most people do a whole lot of things other than consuming media during their day, and computer technology is woefully underoptimized for all those other use cases.
