Here's a handful of typical libertarian positions (though certainly there's some variance): pro-choice, anti-war, pro-civil rights, pro-immigration, anti-drug-war. They don't seem to match your description of "might makes right".

I respect your position. But these to me are window dressing positions cribbed from the Left.

With respect, this feels like moving the goal posts. The position has to disagree with the Left to count?

How about Kelo vs New London? This was the Supreme Court case establishing that the government could use eminent domain to seize people's homes and hand the property to private developers, in the interest of raising tax revenue for the city. Libertarians were against it; liberals were for it. Is that "might makes right"?

What?

Libertarianism basically sees two possible crimes: force and fraud. Totally incompatible with "might makes right".

So libertarians support laws making legal subtle force and fraud, ca. carried interest, private prisons, private ownership of everything, with no commons.

Libertarianism started on the far left, explicitly opposed to private property, largely overlapping with anarchism. Modern US-style right-wing libertarianism basically cribbed most of it but added a property right fetish.

(Dejaque, the founder of libertarianism called Proudhon, the founder of anarchism, a "moderate anarchist, liberal, but not libertarian")
