Star Trek money nits

I had previously expressed my strong objections to the Nokia product placement in the latest Star Trek film and wondered if Kirk's legal guardians would be getting a bill in the mail. Going to see the film again, more issues about money in the future were raised in my mind. The first time I saw the film, Uhura's mention of a drink called a "Cardassian sunrise" raised my eyebrows. But what do you make of the dialogue after Uhura (Zoe Saldana) places her order, when Kirk (Chris Pine) is trying to get with her?

KIRK: Her drinks are on me.
UHURA: Her drinks are on her.

How much do you think a "Budweiser Classic" costs in the 23rd Century? But more importantly, where is Uhura's purse? Or does she just put her thumbprint on some kind of pad to cause a debit to her account? Money is not supposed to exist. If Gillian (Catherine Hicks) saying "Don't tell me you don't use money in the 23rd Century" and Kirk (William Shatner) replying "Well, we don't" in Star Trek IV: The Voyage Home is not sufficient confirmation (given the much-hyped "alternate reality" of this new film), consider Tom Paris (Robert McNeil) telling Tuvok (Tim Russ) that Fort Knox was turned into a museum in the 22nd Century (in the Star Trek: Voyager episode "Dark Frontier"). Even if Paris and Tuvok don't wind up serving aboard Voyager in the 24th Century because of Nero's incursion into the 23rd Century, money should still have ceased to exist on Earth by Kirk's time. (And by the way, does Tuvok still exist in the new "alternate reality"? I didn't see Spock saving any black Vulcans from the temple before it was destroyed.)

When Kirk shows up in a motorcycle to take the shuttle to Starfleet Academy, a man compliments Kirk's wheels, to which Kirk says "It's yours" and tosses him the keys. Is bravado enough to transfer vehicle property in the 23rd Century, or will Kirk need to follow up later with some kind of deed transfer? Have replicators been invented yet? When Kirk went to the motorcycle showroom, did he just say, "Hey, give me a bike"? Well, maybe. Someone who enjoys building motorcycles would probably make more than he or she needs for his or her own transportation. At least it does seem that a starship requires so much time and labor to build that not just anyone can have one.

Earlier in the movie, what do you make of Kirk's uncle or stepfather yelling at him on the phone to not scratch the car up because it's an antique? If humans aren't consumed by the acquisition of things, shouldn't Kirk's uncle have had the decency to turn the car over to a museum?
