But it _is_ still debt right? It is still money owed. It is still money that was spent by the government by taking loans and promising to pay back those loans, again on behalf of the people.
Once in a while, might be worth questioning who they borrowed the money from, what they spent it on, and who they chose to spend it with. Rather than just blindly repeat the pithy line, "but its not the same as regulars people's debt".
The fact the gov can go 34 trillion in debt and a normal Joes Garage can't is actually pretty obvious to people already.
Fundamentally due to interest - you have to pay back people more than they gave you. So just stacking loans to pay loans isn't sustainable. And the US observably does way more with the "loans" they take out than just pay back other loans.
Put another way - if you buy a T-Bill (or other US-backed security aka a source of this debt), what is your confidence that you will get paid on time? I'm assuming very high. But if the US's debt was unsustainable, at some point the house of cards has to come crashing down, right?
And the US does more than just pay loans back by taking out other loans.
