I think you need to avoid taking Musk’s word at face value and instead look at his actions. Avoiding paying rent and severance is not what a financially healthy company does.
The only logical reason I can think of to not pay something you know you’re legally obligated to pay is if you’re intending to declare bankruptcy to avoid paying. Otherwise you’re going to end up paying and pay a load of legal fees on top.
I guess one alternative is effectively taking a risky loan: you are running low on cash but you have a large cash flow coming in the future. Stop paying rent, eventually after a protracted court battle pay your debts with that future cash flow and the legal fees are “interest”.
Neither feels like the actions of a financially healthy company.
