Right, in an addressing scheme that allows 35 trillion /48s, it's easy to see how we'll run out of /64s, not. Sorry, but this line of argument just doesn't make sense to me. It isn't even obvious to me that giving a /56 to every cell phone would be a problem. Every /21 contains about 68 billion /56s. (Yes, I know that we could blow things by foolish allocation policies, but the RIRs don't have foolish policies, in general).
