Anybody who tried has starved to death or needed a bloody revolution to get rid of their dictator and his nomenklatura.

Like Allende, who was democratically elected and then couped by the CIA?

Plenty of communist experiments ran unimpeded (a few are even running right now) and they pretty much all had the same predictable miserable ends.

Oh, and to address your earlier point:

> you fine fellow serfs have made this a fertile land for discussion

Yes, the community is where the value is. But we all congregated here and not on some free and open-source place somewhere else on the Internet. So there must also be some value added by the creators and maintainers of this place, value we recognized and built upon.
