I'm not addressing the general thread, I'm address you specifically saying this "
But small government libertarianism is 100% the politics of Trump." You said Trump, not Musk. And Trump's politics are very much NOT small government libertarianism.
Here is an article from Cato Institute, an actual libertarian think tank:
"the list of Trump policies and postures that libertarians oppose is long and dangerous. He allowed government spending and debt to continue
to spiral upward, increasing the national debt by
$8.4 trillion. Federal
outlays soared from $4 trillion his first year (2017) to $6.8 trillion in his last year. He persists in railing against immigration and
free trade, supports
further expansion of presidential power and seeks to
crack down on political enemies. The Libertarian Party itself
said it best in a 2018 statement: “Whatever libertarian impulses Trump the candidate seemed to have … his actual performance as president stands in stark contrast.”

If you want to pivot away from discussion of Trump and admit he is not a small government libertarian at all that's fine. But for the record Musk also doesn't support small government libertarianism at all. He became the richest man in the world on government subsidies and contracts for Tesla and SpaceX. His path is really "big government for me, small government for thee" which is not actually libertarian either.
