Elon doesn't actually have the cash on hand to buy 51% of the company at market rate (he could release the equity from Tesla or something, but that would be expensive), he wants to do a leveraged buy-out which means we wants to get some other investors to go in with him on the deal at the figure he outlined.
Yeah that is in the same ballpark as (and probably more on the money than) my suggestion. If he gets a few more big shareholders on his side then he could simply put in proposals and sway the retail investors into following.
