This is an especially bad example because basically any crowd scene in anything now utilizes CGI, and the fact she doesn’t realize that proves the fallacy. If you wrote out all crowd scenes, she’d complain movies were too small and sparse.
It's not hard just to change your treatment though. If your script has characters blasting into space, consider having them sit quietly in a room instead.

I don't like to use this example... Trump's hair is his and it's attached by follicles to his head. (I can tell when people have toupee's)
William Shatner on the other hand is as bald as I am.
All art is an abstraction of reality. If the only way someone can enjoy it is if they are sufficiently duped into believing it is real, they are very limited in what they can appreciate
Almost every example I hear of a movie having “bad” CGI is them referring to a single character or creature and not realizing that every single shot in the movie has a set extension or sky replacement or that 80% of the actors body in an action scene is full CG with just their face glued on.
