It is often argued that the US will grow its economy such that the debt is less significant. There is much confusion between the US debt being cited as a ratio of GDP (common among economists) vs net tangible assets (common among businesses and people). For example, after WWII, the U.S. faced its previous record debt-to-GDP ratio—roughly 106% in 1946. By 1974, that ratio had plummeted to just 23% largely through:

a) massive GDP growth with real consumption rising 22% between 1944 and 1947.

b) fiscal discipline where the U.S. actually ran primary budget surpluses in the late 1940s

c) financial repression with the Federal Reserve capping interest rates at around 2.5% while inflation averaged 6.5%. This meant the government was paying back debt with "cheaper" dollars, effectively "inflating away" the debt at the expense of bondholders.

Fast forward to today, there is an often stated belief that the US will grow the economy again, this time with a dramatic expansion into a space economy including orbiting data centers, solar power plants, asteroid mining, space manufacture - all leveraged with robotics and AI. Let's be generous and assume this actual happens and that it happens soon - what mandate is there that this massive space economy will be denominated in US dollars or even be part of the US economy? SpaceX has already launched numerous satellites for foreign countries. What is to stop them launching a space economy that will be owned under a "Flag of Convenience" from an offshore tax-free zone, perhaps even denominated in crypto? Will we then confront this massive off-planet economy with "space-tariffs" in order to import the value-added component back into the US? The U.S. debt can only be "grown away" if the value-added activities (mining, manufacturing, computing) remain registered in the U.S..
