Funny enough, virtually none of Elon Musk's business ideas are financially viable without the government keeping them afloat. Hyperloop wasn't even technologically viable, what a fantastically stupid idea that was.
The reason I have never trusted Elon as part of MAGA is that he's always been a grifter. Tesla is one of the most overvalued companies in the world right now (still), and has rode its stock price to impossible heights via hype, lies, and unfulfillable promises.
The same is true, to a lesser degree, of SpaceX. While SpaceX has made rocketry more economical than NASA ever could, due mainly due to the Senate not directly managing the internal affairs of government contractors, Elon has made one fantastical promise after another with SpaceX. Wasn't his first manned Mars mission supposed to be this year? Artemis has already orbited the moon; Starship's reusable heat shield remains in the realm of speculative fiction.
I've always been skeptical of Elon and am somewhat relieved to see him exiting stage left.
