I'd be inclined to aggree with you were it not for the way Peach specifically worded his audio diary: "...pick up some choice goods not available in a remote place like Rapture, you know: beef, real tobacco, just a little extras."

Because he says they aren't in Rapture it stands to reason that it's not that they're just really expensive.
