What is a good thesis statement showing that Romeo and Juliet don't love each other but are in love with each other's physical appearances?

Romeo and Juliet are young star-crossed lovers from feuding families. In act I, scene 5, when Romeo first sees Juliet, he immediately comments on her beauty and compares her to a rich jewel. Perhaps the most telling line is line 55: "For I ne'er saw true beauty till this night." Romeo and Juliet briefly converse. As people are leaving, Juliet inquires about Romeo's identity. When she finds out who he is, she sadly exclaims, "My only love sprung from my only hate! Too early seen unknown and known too late!" (1.5.140-141). This reveals that she loved him almost as soon as she saw him. She knew not his name, nor anything of his character.
The chorus at the beginning of act 2 also mentions that Romeo is bewitched by "the charm of looks." Romeo's speech in the orchard details the various physical characteristics of Juliet that he is enthralled with. Soon thereafter, the young pair professes their immense love for each other and decide they must get married.
Throughout the play, much emphasis is placed on beauty and physical characteristics. When anyone speaks of beauty, love is usually involved. When Romeo is speaking to Benvolio, they speak almost exclusively about the physical beauty of women. Likewise, when Juliet and her mother are discussing marriage, they also focus on the physical appearance of the proposed suitor.
