I think it's because Musk doesn't want any sort of Left, Centrist or even Centre-Right governments that believes in concepts like regulation and taxation, anywhere. It's a weird moment in history when it seems like any old grifters can get into power anywhere, and he wants to use whatever influence he has (money, social media coverage) to promote the sort of Extremist Right Libertarian-tinged nutters into power where they can basically just slash away anything that he doesn't like.
I don't know whether it's just a sad attempt to turn personal billions into trillions, or whether there's a nefariously ulterior motive to take increasing direct control of parts of the world (by replacing Government functions across the world with his own services), it's pretty unprecedented to have a single person with this combination of personal wealth, exposure, and a weird base of fanboys cheering on his every move.
I'd just be happier if his gurning mug wasn't plastered across the new pages daily. Unbelieveable he can't think of anything better to do with his time than this.
