Yep, I also believe that we will have a Minsky Moment on the entire Muskonomy.
Given his political involvement, I would assume that the maximum end date for this house of cards is the date when Trump is no longer in power - which is less than 4 years away. The real date is probably much sooner, but who knows when ?
But that then means that Musk has a strong incentive to keep Trump (or some replacement that will similarly let him do whatever he wants) in power past these 4 years.
Buying time to get the rocket finished that he will ride escaping his creditors to Mars. That would be a badly written plot even by the standard of cheesy comic books, but somehow it all makes sense from that angle. (no, I don't believe that he would ever get within explosion range of a rocket engine ignition)
