Original post by viddy9I reject your premise, because communism - actual communism - has been attempted on a large-scale in at least two cases: in the Ukrainian Free Territories and in a good proportion of Spanish regions during the Spanish revolution which occurred during the Spanish Civil War.
As George Orwell described, when talking about the Spanish communist societies:
"Up here in Aragon one was among tens of thousands of people, mainly though not entirely of working-class origin, all living at the same level and mingling on terms of equality. In theory it was perfect equality, and even in practice it was not far from it. There is a sense in which it would be true to say that one was experiencing a foretaste of Socialism, by which I mean that the prevailing mental atmosphere was that of Socialism. Many of the normal motives of civilized life—snobbishness, money-grubbing, fear of the boss, etc.—had simply ceased to exist. The ordinary class-division of society had disappeared to an extent that is almost unthinkable in the money-tainted air of England; there was no one there except the peasants and ourselves, and no one owned anyone else as his master... I recognized it immediately as a state of affairs worth fighting for...so far as one could judge the people were contented and hopeful. There was no unemployment, and the price of living was still extremely low; you saw very few conspicuously destitute people, and no beggars except the gypsies. Above all, there was a belief in the revolution and the future, a feeling of having suddenly emerged into an era of equality and freedom. Human beings were trying to behave as human beings and not as cogs in the capitalist machine."
And, as Leval summarises:
"Very quickly more than 60% of the land was collectively cultivated by the peasants themselves, without landlords, without bosses, and without instituting capitalist competition to spur production. In almost all the industries, factories, mills, workshops, transportation services, public services, and utilities, the rank and file workers, their revolutionary committees, and their syndicates reorganized and administered production, distribution, and public services without capitalists, high salaried managers, or the authority of the state.
Even more: the various agrarian and industrial collectives immediately instituted economic equality in accordance with the essential principle of communism, 'From each according to his ability and to each according to his needs.' They coordinated their efforts through free association in whole regions, created new wealth, increased production (especially in agriculture), built more schools, and bettered public services. They instituted not bourgeois formal democracy but genuine grass roots functional libertarian democracy, where each individual participated directly in the revolutionary reorganization of social life. They replaced the war between men, 'survival of the fittest,' by the universal practice of mutual aid, and replaced rivalry by the principle of solidarity....
This experience, in which about eight million people directly or indirectly participated, opened a new way of life to those who sought an alternative to anti-social capitalism on the one hand, and totalitarian state bogus socialism on the other."
Therefore, my opinion is that people should use terms correctly, because 'anarchist' is often completely misunderstood and so is 'communist', meaning that the only real term left-libertarians can actually use is 'libertarian socialist'. Whilst the term is adequate - socialism is about common ownership of the means of production, meaning that it can exist in the form of state socialism (i.e. in mixed-market economies such as Scandinavia, or in full such as in the extreme Soviet Union) or libertarian socialism, I'd rather people just used terms correctly.
