The definition I found for "Generica" is: "Regions of the urban landscape of the United States that are indistinguishable from one another because they have the same retail outlets, motels, and housing."
That's from The Free Dictionary, citing some company. While I understand it (and have experienced that situation (shudder), it's definitely not a common understanding of "generica," which, in my experience, is used in the pharmaceutical industry to lump generic drugs together.
Back in the '70s, I believe, there was a movement to introduce generic foods etc into the marketplace. They typically had very simple labeling and didn't rely on advertising (although one large grocery chain in my area spent quite a bit of money advertising that they had introduced generic goods into their product range). You had to be careful with the generic foods since the quality varied considerably between varieties.
I suspect that "generica" is being used in that sense in the cartoon.
I agree that #7 doesn't really fit here. Even in the pharmaceutical industry, generic drugs are totally legal.
