That's the sort of stunt that would land him and a lot of people involved in the "doing jailtime" sorts of hot water. I REALLY doubt he'd go for a launch without FAA approval. (And it's not just FAA, there's range safety, launch equipment operations, etc. Unless he's got some underground launch silos hidden somewhere, it'd be very hard to prep a Falcon 9 for launch without anybody noticing or having a say on whether they can light the blue touch paper.
