Your link uses a very big "assumption" that will probably not happen, but if it does we are toast, namely...
If interest rates are 1% above projections for a decade...unlikely under Kevin Warsh.
2026-04-22-Interest costs will exceed

"For example, if interest rates were remain above projections this year and be 1.0 percentage point above projections through the decade – bringing the 10-year Treasury note from an average 4.3% over the decade to 5.3% – it would add an additional
$3.5 trillion to the debt above projections. By 2036, interest costs would total $2.7 trillion – nearly 6% of Gross Domestic Product (GDP). Debt held by the public would rise close to 128% of GDP, compared to 120% under current law projections."
I'm not ready for "the sky is falling" scenario just yet.
