Exactly, you think it's all personal responsibility. That the economics of culture have no impact (or are desirable?). Totally ignoring that access to culture is not deliberate. There are massive network effects and constant, unavoidable advertising. Your very tastes are shaped by society around you.

And lol at lemmy as an example. Social media and content aggregation is even more homogeneous than film/print/music/food. The fact that tiny countercultures exist doesn't disprove that.
