Are you immortal? Do you have an income vastly higher than the servicing cost of that debt? Do you owe the large a majority of that debt to yourself? Are you able to, if push came to shove, tell your external creditors to go fuck themselves and dare them to so much as try to collect on the debt you don't feel like paying? If you can't answer "yes" to all these questions, you aren't the US and have a debt situation that has absolutely nothing in common with the US debt.
Worth pointing out that credit scores are completely detached from the government. They are entirely private industry, that is collecting and selling your financial info without your consent or opt in. If you were born before 2004, then they have also accidentally leaked literally all your personal info to the dark web, with literally 0 consequences.
Credit scores require you to get some kind of debt. This is because it's not a score of your financial health. It's a score of how reliably you repay your debt.
