It worked pretty well in Spain during the revolution. George Orwell fought in Spain alongside anarchists and Marxists, and wrote a book about it. He described his experience as:

"I had dropped more or less by chance into the only community of any size in Western Europe where political consciousness and disbelief in capitalism were more normal than their opposites. 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."

The wiki article on Spain during the revolution goes on to say:

"The anarchist held areas were run according to the basic principle of "From each according to his ability, to each according to his need." In some places, money was entirely eliminated, to be replaced with vouchers. Under this system, goods were often up to a quarter of their previous cost.

Despite the critics clamoring for maximum efficiency, anarchic communes often produced more than before the collectivization. The newly liberated zones worked on entirely libertarian principles; decisions were made through councils of ordinary citizens without any sort of bureaucracy. (The CNT-FAI leadership was at this time not nearly as radical as the rank and file members responsible for these sweeping changes.)

In addition to the economic revolution, there was a spirit of cultural revolution. Oppressive traditions were done away with. For instance, women were allowed to have abortions, and the idea of "free love" became popular. In many ways, this spirit of cultural liberation was similar to that of the "New Left" movements of the 1960s."

I'd say that not only do humans work like that, but, in fact, they worked like that extremely well.
