Paraphrased feel to it: shows her contempt for his decision making.
“Look, we all have wishes; granted”
Everyone has hopes, dreams. That is natural. But not many people actually manage to achieve the things they dream of.
“But who has wishes granted?”
The speaker’s biting humour and sharp wit is continued through the pun ‘granted’ - the first instance on acknowledging that we all wish for things; the second, that he has been literally granted his shallow wish.
"Him."
Minor sentence to show how bitter she is about it. Also conveys his isolation and highlights his hubris (overwhelming pride and presumption that he ‘deserves’ this ‘gift’).
"Do you know about gold? It feeds no one; aurum, soft, untarnishable; slakes no thirst."
Gold is beautiful, but it is essentially useless; it cannot provide the basic necessities for life. The rhetorical question suggests she is annoyed by his foolish choices - they gain nothing from this “gift”. Gold is personified to make the key point relating directly to the Midas myth: greed leads to destruction, not gain.
"as the blue flame played on its luteous stem. At least, I said, you’ll be able to give up smoking for good."
Luteous-yellow tinged with green or brown. Word derived from the Latin name of a plant used to dye things yellow: his cigarette has turned to gold. Her criticism of gold ends abruptly with her contrasting joke about his being able to quit smoking permanently.
