So I completely agree with this statement, but I completely disagree with the metric you've chosen to illustrate it.
"National debt" only exists due to the martingale of the Federal Reserve neutering the government's own monetary sovereignty. If we need to have an inflationary currency, then the new money should be spent by Congress on deliberate public goals - it's another tax.
You can tell "national debt" is a dodgy metric because it combines two very different things into one scary-in-the-context-of-household-finances thing. The portion of "the debt" that is Treasuries held by the Federal Reserve is the lesser bit of monetary creation that was actually spent for public goals, in spite of the fake "fiscal responsibility" narrative. It is moot as far as debt goes - nothing actually happens if it compounds to infinity.
The other portion of "the debt" that is held by private/foreign owners is the government functioning as a bank account of last resort, and could very well just be at the central bank instead.
What we currently have is a dog and pony show to pretend that we don't have this centralized fountain of money, in order for the financial industry to keep getting the first cut of low interest loans (which have mostly gone into bidding up the asset bubbles).
