I've noticed a collectivist under-current in some of the thinking of folks involved in the Free-State Project and other libertarians. This collectivism is subtle but real.
Sure, "live free or die" as a personal motto or ethic is ultimately an expression of individualism. But many libertarians incorrectly diagnose the ills of modern statist society to be due to a lack of willingness to die for one's liberty on the part of the masses. They are asserting something along the lines of "if only people were more generally willing to die for their liberty, we'd all be truly free." The idea is that a tyrant can't dominate a people composed of individuals who are mostly willing to die rather than be enslaved to the tyrant.
But I think this is subtle or stealth collectivism because dying for one's liberty is not really dying for one'sown liberty (you can't be free when you're dead). Instead, dying for liberty is dying for the liberty of others. And such self-sacrificial acts - while laudable in their own right - are not performed in one's own interests but in the interests of the collective. Those who subscribe to the theory that we are not free because enough people are not willing to die for freedom ultimately have no faith in the self-organizing nature of society composed of uncoordinated individuals pursuing their own, independent ends.
Even if it's just an expression of one's personal credo or motto, I still cringe every time I read the phrase, "Live Free or Die."
