It is well understood that weakness invites challenge but in reality it doesn't just invite challenge, it brings violence. Only the incredibly secure have the luxury of being weak. The cycle of history shows that strong men create good times, good times create hard times, and hard times create strong men. Why then would anyone intentionally become weak and welcome hard times? In our personal lives we do not have the luxury of being weak. You must protect your family and yourself and as the world becomes more and more dangerous this is becoming harder and harder to ignore. Finally, my fellow libertarians seem to have forgotten that nothing exists in a vacuum and no matter how much you respect individual rights in your nation there will always be those who look at you with greed from another nation and seek to crush or conquer you. Weakness at every level brings destruction. So do whatever you can to not be weak.
