The reason why I don't believe they need a 70 billion dollar deal, is that Elon doesn't plan on buying himself out! And if they take the same structure as SpaceX, I would expect at least half of current shareholders to stay in the company, as well as most employees. That would then require 20-30 billion, on the high end. Far more feasible and a great strategy, really. Everyone's that's long stays, everyone that's medium to short term gets a nice bonus with the 420 payday, Every short dies, if everything goes as planned.
