Everyone is happy enough to give Elon (and others) more and more leverage to buy politically strategic companies (this is not that, this is probably just an ego buy for him, something to kill time because he can).

I was worried about him selling out (from an overall market and even index perspective when they were going to bend rules), but it looks like largely the whole situation is predicated on the idea that he can't or won't sell. I don't know how exposed the market is but it doesn't feel good.

No shit. That's why, even if it's an exaggeration to call the entire stock market a pyramid scheme, you can't justify the claim that it's entirely "underlying business activity that drives total returns". That's the real question (from which dividends are, yes, a distraction).
