Majorly cheap, but you're also highlighting a massive bystander effect. "What hope do I, one citizen, have of changing anything?"

The other point is (arguably) that government should not be risking bankruptcy for the sake of innovation. Which in the cases of government bankruptcy, was not the reason for insolvency anyway. So then it comes back to mismanagement, where maybe the better analog is personal bankruptcy. If an individual came to you and said they were declaring bankruptcy because they had spent more than they made for the last 20 years, you probably wouldn't have much sympathy.
