That’s a fair response. You’re absolutely correct that the personal mortgage analogy is used to argue that governments can’t (or shouldn’t) take on certain debt loads. On the flip side, I’d argue that mortgages and personal finance in general doesn’t tell us much about how governments should treat debt. The nature of government debt, how it’s financed, and what it’s used for is just so different from personal debt that any analogy between the two gives us very little information.
