It doesn't matter how much money you print if your debts are USD denominated. If for example Tonga has double their currency in circulation with a debt of Y USD tomorrow they will still owe Y USD and their currency will probably be worth half of what it was before.
In the case of the dollar if you suddenly double the supply it's not just the US national debt that is affected, it's all the secondary financial products indexed on dollar that are affected: debt from countries and private companies across the world, commodities and all transactions between countries not involving US that are dollar denominated. So in a way the value of a single dollar is diluted but it's diluted over a much bigger pool of participants.
That's the main reason printing money is cheaper to US as is reflected on the bond market, just look at supply vs inflation around the years following the global pandemic.
Living beyond their means is very relative. When credit is virtually free for years it makes sense to run 10x leveraged, the problem is when interest rate rises and you have to deleverage without showing too much that you don't have that much money as failing to do so could result in a death trap spiral.
