Classical Liberalism, or as it is called in the US Libertarianism, is a utopian belief that people are by and large capable of living as rugged individuals. Since most people can’t or won’t live self-sufficiently something ends up being done to protect these people from themselves and minimize the chance they will rise up in food riots. That something is most often a socialist or welfare state government. And the worst kind of socialist government because the people have imbibed what they liked about libertarianism (do your own thing and look after yourself) so the intermediate institutions that provide some protection from the state such as families and fraternal organizations have withered or died away
That’s not even close to what Freedman advocated.
