I don't think this song is sarcastic at all. I think it's offering up a peace of love, but it's unbearable because whomever the person is writing about, when it refers to "she" that, this persons words won't fight her love (the paper tigers are no match for the predators inside her). The writer faces their own challenge of never having found the right love for themselves. Looking in on other's lives, and love being a shiny toy inside somewhere the person can't grasp it. The writer is wishing both of them love to be found, generously, but is expressing the painful realization at times, that words can't make it right, or happen.
