What finality does Gatsby create when he first kisses Daisy?

Gatsby's Romantic pusuit for Daisy Buchanan is ruined when he kisses her. Gatsby attempts to transcend materialism and superficiality of the 1940's American jazz age with a Romantic love, transcendent of reality and the social deterioration of values.
