Or alternatively respect the democratic process an stop trying to get around the rule of law simply because the president isn't being given the power he's demanding.
A much better way forward, I'd say.
But keep in mind that in the US system there is law that takes precedent over each other, to iron out exactly this sort of issue.
Federal regulation is defeated by codified statute which is defeated by constitutional imperative.
So in this case, the last Congress gave statutory permission to spend on programs, but that can't override constitutional obligation to service debts.
Constitutionally, the president must not default, and he cannot borrow money. Treasury must pay debts, and spending on other programs is second in priority.
