While I agree with your sentiment, I disagree about it not being about Tesla. If Elon is using his TSLA shares as leverage to buy Twitter, he just substantially increased his debt and gave his enemies a target share price to get TSLA to in order to margin call Elon Musk. If that happens, he may be forced to sell some of his TSLA stake and reduce his ownership, which would make a hostile takeover easier.
Sound far fetched? Look what Elon just did to Twitter.
I think folks concerned about Elon getting a margin call can relax. I'm reminded of a line in my favorite novel:
"The sort of American you hint at has wealth, not merely money as you understand it, and a great many influential friends..."
--Gorky Park by Martin Cruz Smith
Elon Musk has powerful enemies, but also many extremely wealthy friends and allies. A margin call caused by a dip in TSLA would be a short-term need for funds or credit. I'm quite sure Elon could handle it without selling TSLA if he wished. He has relied on friends before.
He is not like you and me. His phone Contact list is full of billionaires.
