No, they don't. Contracts are enforced by the threat of the state's monopoly on violence. If the US goes bunk, who exactly are you going to to get your money? The courts are bunk too.
Even if the government exists, if Trump and Musk hold the payment system and you somehow get a judge to tell them to pay, they can just say no. Then what? Are you going to go Rambo? They hold a monopoly on violence and imprisonment.
This is why government's need to be set up with so many layers of indirect power and checks against direct power. this is why the military (should) have no role in governance.
