Elon's ventures are big enough now that they are a key thing in the politics game. I 'd wager one aspect of this is making sure his voice stands out (to be able to influence politicians 'bottom up').
What I missing about this is that is he actually going to take it private or fold it to some other company with massive over valuation like Tesla... In later case it will make money for him, because people are stupid... In first case it really seem expensive wasteful thing, billions buy lot of lobbying power...
