The problem is never the amount of debt, but the backing of that debt. It is true that government debt is useful: money is a government liability (zero coupon, infinite maturity for cash) and treasuries are a safe security (until we default) in a world where safe securities are scarce. In the 90s, people were worried that by lowering deficits we would create a shortage of government debt and safe assets. This was completely misguided because we can always issue more debt and use the proceeds to buy valuable assets to finance the repayment.
When people say that they are worried about government debt, they mean relative to the ability to repay. Since we see that increases in debt don’t go towards increasing our ability to repay it but rather decrease it, it is natural to say that we want government debt to stop increasing.
I actually think that there is not enough Treasuries around as we can see by the convenience yield that they have. This convenience yield says that we could profit by issuing debt and investing in real assets, turning the federal government into a massive bank (which it kind of is). Yet issuing more Treasuries and then wasting the proceeds is not sustainable.
