I think people are right to be nervous about the brinkmanship around the debt ceiling. We pretend to be about to default every couple years, then at the last possible second, we say "haha, just kidding". It's possible that one day, the "haha just kidding" part might not happen.
That said, I'm not sure that this is any more dangerous than any other kind of debt. In the past, people considered US government debt to be equal in safety to a savings account. It is definitely a little more risky than that these days. The FDIC has never said "just kidding about that insurance!"
