Paying back creditors in severely devalued dollars isn't exactly meeting obligations. Presumably the ratings would take this into account.
That said, I agree these ratings don't have much basis in reality. As others have commented, look at how S&P and similar organizations rated subprime debt. They're part of the Wall Street club. They might nibble a bit on the hand that feeds them for political reasons, but they certainly aren't going to bite it off.
It's pretty clear that a AA+ rating for US debt is as much of a joke as AAA. The token 'downgrade' gesture just adds to the absurdity.
Issuing currency to back the "debt" is not a devaluation. Imagine you hold $100k in treasury bonds. The Federal reserve then prints a bunch of money, buys those bonds from you, and gives you cash. Are you then going to be willing to pay twice as much for a car, twice as much for a loaf of bread, etc? No. Your financial position has not changed. No change in your financial page, no inflation, no devaluation. All buying back debt with currency does is replace one piece of paper backed by the US Gov with another piece of paper backed by the government.

It doesn't matter if you're "willing" to pay more for things or not. If the Fed monetizes debt, more money enters the system, there are more dollars bidding for the same amount of goods, prices rise, and creditors will get less for their money. Simple supply and demand.
If you were right, the Fed could just write checks for the whole $14.5 trillion debt in one go and we'd have a balanced budget overnight. Do you think that would be a good idea? Hell, why not create a quadrillion or two more on top of that and make us all millionaires??
