Maybe that's one of the reasons they didn't go that route? The subsidized cell phone business model can suck for consumers (sorta the point Bezos was making), but requiring a minimum book purchase is still something some people might go for.
I have no idea how they'd implement it, but I suspect you'd pay a monthly fee that "earned" you X number of books. You'd hope they wouldn't let you "forget to buy enough" and thus lose your Kindle service.
