It's fun to speculate with stuff like this. Is it a show about the Tower family? (Presumably the family would be independently wealthy, like nearly all soap families are. Who wants to get caught up in the adventures of poor people? That hits too close to home!) Is there a character named Ivory? Is it all about the romance and intrigue at a fictional university? (Academics are sometimes accused of living in "ivory towers" and being out of touch with reality.) Or is it a concept show about people who are removed from real life?
I lean towards the Tower family meaning, but something else might be just as valid. Maybe that's one of the subtle reasons Lois was mildly attracted to Lex, because her "romance" with him reminded her of the trials and tribulations of the Tower family.
Anyway, it's a neat loose end any writer can play with.
