>>>She did resist the idea that there was such a notion as a “moral duty,”
Only when the notion of “moral duty” involved self-sacrifice. That’s rather different.
So then, I'll posit the same question I asked in #63.
Do you think Ayn Rand would have been willing to defend her beliefs with her life?
Let's say that she had been able to establish a nation (or city state) of "Galt's Gulch" full of her die-hard adherents, all pledged to pure Randian Objectivism. Rand was able to write the Constitution and all the citizens voluntarily comitted to living according to Randian principles.
If Galt's Gulch came under attack from outside, would Rand have been willing to place her life in mortal peril to defend Galt's Gulch so that others might continue to enjoy the Objectivist paradise? Would she have expected others to?
