It does not make much sense that the two would be one.Fascism is very much at odds with libertarianism.
what some far leftish wags claim notwithstanding.
The novel, "The Moon is a Harsh Mistress" has always struck me as an send up to libertarian views. It is one of Heinlein's more well-known works from 1968. In it, the citizens of the moon are rebelling against the tyranny of an oppressive Earth that extracts their resources without reasonable compensation or consideration to their drain on resources.
