If you buy a car, and do not pay for it, it gets repossessed and you credit rating takes a hit.
If the us gov does not pay it's debt, as in the legislation that they have past that has costs associated with it, then the work does not get done and the governments credit rating takes a hit.
A person is limited to what they can buy based on their credit rating.
The legislature can go on passing legislation. It may cost a bit more, but they can go on doing so.
So, if you think about it just a bit, and you do not like the spending going on, then you need to elect legislators that will spend according to your beliefs. Not get to a point where the credit rating of the country is hurt. And, by the way, the debt limit goes up anyway, as it always has.

Thats 3 times for Obama admin, 7 for Bush W admin, 4 for clinton admin, 4 for HW Bush admin, 18 times for Reagan admin, 6 times for Carter admin. And so on for many years in history. And every time without real opposition. Only when the tea party took control of the repub admin did it become an issue. And only then did the repubs get the cons to believe it was a good idea.
