Here's the exact line from the part you're referring to. "You wanna know what my vision is? Dollar signs! Money! I didn't build this ship to usher in a new era for humanity. You think I wanna go to the stars? I don't even like to fly. I take trains. I built this ship so that I could retire to some tropical island filled with naked women. That's Zefram Cochrane. That's his vision." He didn't mean "I'm going to fly the Phoenix to an island filled with naked women", he meant "I'm going to sell the Phoenix, get rich, and retire to an island filled with naked women."

He said in dialogue that he was referring to the idea that the fame and fortune the invention would bring him would consist of money and naked women
Maybe he was a fan of the ZZTop song "Planet of Women".
