You appear to have misunderstood the role of the SEC. They will investigate civil violations of securities laws but there has been no credible allegation of such here. They don't take responsibility for stock valuation.
Well not really. So you're wrong here yet again. What's the total value of all minerals and resources on Earth. If SpaceX had a goal to colonize other planets or asteroids and the sum total value of the minerals and other resources that they had access to was greater than the value of what is here on earth, what exactly is a lie about that statement?
Of course, the aspiration and attempt may fail, but in this quote they did say if.
You're letting your dislike/distrust of Elon Musk cloud your judgement. If you don't like him or don't like what he says, don't buy shares in his companies, don't buy his products, and don't read what he writes.
Nice strawman, but that's not what I said.
They can, and do, intervene in things like lying to investors to inflate valuations.
