There's a dissonance between allowing complete freedom without intervention and keeping the market truly free - if an organisation can simply buy all it's competition and expand forever, that's just a monopoly which is a closed market.

As for socialism - I grew up in a kibbutz, which is one of the only examples a successful socialist system (imo). And this too, is time limited. My reasoning being having a small group where everyone know each other and decide to join of their own volition. Most kibbutzim failed after the 3rd generation - people did not want to share anymore (and took some very bad financial decisions).
