NASA has not booked or given any indication that they care about BFR specially for humans. There is a large difference between being the primary costumer of SpaceX and BFR. If NASA wants to fly Astronauts on BFR, then SpaceX can tell them that they have to pay for human rating. SpaceX development targets that, they just don't go threw all the paper work. Also, the reality is that this 'human rating' is really not clear at all. NASA has no clue how to human rate anything because nothing was really human rated according to the NASA guidelines. They specially have no idea how to human rate a shit that goes to Mars. Every-time they do a rating it is a new and different process. The problem with this process is well known in the industry. The reality is SpaceX simply couldn't develop it fully human rated because its not clear what that even means. All they can do is build the best possible ship and see where the dice fall.
