Debt does have a statute of limitation that varies state to state [0]. So even if there is a trial and judgement, after a certain amount of time it is invalid and there is no legal recourse to collect (although collectors will still ask).
I think the issue here is that this debt is not subject to the statute of limitations. Some other federal debts- student loans- have similar exemptions and special considerations.
