There are hundreds of people who know C++, live on the west coast and talk like a pompous idiot. Elon Musk is one candidate of hundreds.

You should do some statistics research and realize that just because one celebrity matches your description doesn't mean that they're the sole candidate for your search. I'd argue that you're acting pretty clueless here, especially since Elon himself has denied creation of the spec. Without any further evidence, you'd need something utterly damning to make people believe you. There are real ways that you can prove that you built Bitcoin; you can step forward with keys to the wallet with the genesis block or you can render passwords to any of the accounts Satoshi used online. Not only has Elon Musk done neither of those things, he's outright told people that he didn't build it when there was every incentive in the world to acknowledge himself as Satoshi.

If anything, I can see why all these Bitcoin accusers never got anywhere as SpaceX employees. Rocket science doesn't make progress with guesswork...
