Nobody would enjoy having a diamond without advertising. Maybe a child, to put with her collection of other rocks and shiny things. While I agree with your parent that advertising can help people enjoy things more, I don't agree with the implication there's a positive side to ads. Everything I can think of that people enjoy more because of advertising, they'd probably be happier not enjoying. Also: advertising can make you enjoy things less (usually things you already have). Maybe things you'd be happier if you enjoyed more.
