The problem is is that the amount of debt is percentage of GDP, and therefore the interest rates that we need to pay are significantly higher now. This kind of analysis is hopelessly naïve without taking into account overall macro situation.
You can't print money to pay off your household debt.
It's a different beast altogether subject to entirely different rules and incentives than household debt.
The debt can never be paid. It's by design.
No country other than New Zeeland bothers to properly account for the asset side of the national budget. Increasing liabilities is fine if there's a corresponding increase in assets. But most countries are basically guessing about the second half. (This is also why we see so many wasteful privatisations where national assets are sold off for way less than they're worth)
