From this at City Comforts and following the links trail back it seems that I was right in my characterisation of Randism (is that the right term?) here.
I remain suspicious of anyone who claims to have the one and only answer.
UPDATE: The Adam Smith Institute are holding a seminar on Ayn Rand, which prompts a nicely waspish comment. Take note of Mr Smithson Morton since I don't suppose you will be seeing his name at the ASI again.
