That's clearly enough obligation to you. should someone come to you wanting a new $400 hammer, surely you would make it, right? and because you made it, that person is obligated to buy it, you say? if they don't buy t, they would be in default, and subject to your righteous ire! fine.
In the real world, when spending exceeds funding, spending gets cut. either by rational self control, i.e. not ordering things you cannot pay for, or by creditor control, businesses and employees failing to extend you credit.
I've been employed by companies going under. There's no good feelings when you go to work, and suppliers have cut you off and you don't know if you will be paid for your work and time. I don't wish that on anyone. yet, at the same time, continuing this charade is just extending this to more people and companies. when in a hole, stop digging.
anyone doing business with a shaky customer prices that risk in. making the full federal debt shakier by adding to it, raises the risk, and eventually, the price. (comments about greece and printing money deleted. see? I'm trying to show restraint, too.)
i guess it really comes down to obligation. if i order goods from you, run out of money, then cancel the order, i don't feel obliged to pay for the cancelled order. if there was a cancellation fee, i'd feel obligated by that. if i'd taken delivery, and there was a restocking fee, i'd feel obligated by that. if i hired you to pressure wash my driveway, you got started, and i cancelled halfway thru, i'd be liable for half the fee, and maybe some transportation costs. That's the way the world works.
I see no reason why it would be better to let them finish the driveway and declare that since i can't pay in full, i won't pay at all. or until some undetermined time in the future, when the political winds are right. it would be immoral for me to do it, i don't understand why feds doing it would make it right.
You seem to hold the view that
It is partial default. Financial promises made by the government are broken.
Every purchase made, or employee hire, or debt the feds acquire is done under contract. those contracts have cancellation terms. engaging those cancellation clauses doesn't put anyone in default. mind you, there would be work involved in this process, and there seems to be nobody in office who has the slightest interest in doing it, or seeing it done.
that is a political issue, not economic, moral, or administrative.
