"Muh NAP" is not the basis of libertarianism, nor is abiding by it.
Certain thoughts can render one not libertarian, at a foundational level, without action, or rights violations, and simply "not violating rights" isn't the foundation of liberty or libertarianism.
The belief in free will, and the meritocratic notions which spring from anti-determinism - THE ORIGINAL MEANING OF LIBERTARIANISM - are the foundation, not muh NAP.
Believing one's value is determinist, and not by their will, is anti-liberty. Can't be anti-liberty libertarian.
Like even NAP as a phrase even came so long after political libertarianism. This isn't a thing. Even in American right-libertarianism, muh NAP ain't the root, and it got on fine without it for many years.
Libertarianism didn't poof into being when the NAP was coined. Ridiculous.
