Now, if we put those two hypothetical imaginings together -- can you imagine that maybe, just maybe, Tesla could buy-back enough of those depressed shares to effectively increase Elon's ownership percentage, and nudge his voting control up to where he will feel more comfortable?
You seem to like the idea of Elon "lowering Tesla's valuation initially", so that is one hypothetical...but I think we've all seen over the years many different reasons (or lack thereof) for irrational drops and sustained depression of Tesla's valuation. Combine any of those with lots of cash-on-hand, and the company can effectively buy back shares to increase everybody (including Elon's) percent ownership. If, in this future, Elon is already close-ish to his desired threshold, it seems reasonable to imagine Tesla could decide to do this to get over that hurdle.
