I think you're totally wrong on this. Tesla didn't waste the first mover advantage. They benefitted from it whilst it existed, but Electric vehicles turned into a commodity, which was entirely expected and there's no moat.
You've explained yourself why it would be untenable for Musk to pursue becoming the biggest car manufacturer in the world - if he succeeded in that goal... he would have succeded in shrinking the value of the company significantly.
It's pure logic that Tesla has to pursue bets that would justify billion dollar valuations and being a car company isn't that.
