Humanity has experienced such total free economy. It took 1000 years for Europe to break out of the feudal system where inherited property based on land concentrated power at the very top. It took four centuries of combined effects of the renaissance, age of exploration, the industrial revolution and new found serfs in the colonies to break the feudal system. Pure libertarian solutions take centuries to take effect, they require seismic paradigm shifts and the breakdown is very violent. Culminating in a 30 year world war. (According to Churchill world war I and II are just one war spread over three decades).
Pure libertarianism is just marginally more practical than communism. Communism simply will not work because it disconnects incentives from effort. Libertarianism naturally leads to oligarchy. Liberal democracy, founded on acknowledging the usefulness and sinlessness of the profit motive to the society but moderated by large number collectively holding more power than any small group of oligarchs is what would work to give justice, peace and liberty to most people.
