Ultimately, wealth, beyond what you physically control, is only real if everyone else agrees that it's real. Otherwise you're just tapping a rock on another rock and walking out of the store with eggs.
And that 36 trillion in debt was created with a complex dance out in the open; I've got some paper who wants some paper I'll give you number go up in a year if you give me number now! And we can all look at the ledger and there are people in robes in a locked room who protect the ledger when we're not looking.
If instead we've got a ledger, left floating around the house and garage, and all the people in robes have been fired, and all of a sudden we don't need that tedious "pass laws" stuff to "balance the budget" and the ledger's full of sharpie scribblings, what are the numbers in that ledger? The fewer people who believe that number or ledger, the fewer eggs you'll be able to buy by tapping your rock on someone else's rock.
The same goes for other ledgers -- stocks -- the US stock market is trusted only because people trust the numbers that are reported. If you've fired all the regulators, auditors, and enforcers, your stock market will lose trust, and again, the numbers will be the same but worth less because nobody will believe anything.
