I'm sure you commies out there will fail to see yourselves

in this description by Murray Rothbard, but it's you:

It is no accident that it was precisely the economists in the Communist countries who led the rush away from communism, socialism, and central planning, and toward free markets. It is no crime to be ignorant of economics, which is, after all, a specialized discipline and one that most people consider to be a "dismal science." But it is totally irresponsible to have a loud and vociferous opinion on economic subjects while remaining in this state of ignorance. Yet this sort of aggressive ignorance is inherent in the creed of anarcho-communism.

The same comment can be made on the widespread belief, held by many New Leftists and by all anarcho-communists, that there is no longer need to worry about economics or production because we are supposedly living in a "post-scarcity" world, where such problems do not arise. But while our condition of scarcity is clearly superior to that of the cave-man, we are still living in a world of pervasive economic scarcity.

How will we know when the world has achieved "post-scarcity"? Simply, when all the goods and services that we may want have become so superabundant that their prices have fallen to zero; in short, when we can acquire all goods and services as in a Garden of Eden — without effort, without work, without using any scarce resources.
...
The fact that the abandonment of rationality and economics in behalf of "freedom" and whim will lead to the scrapping of modern production and civilization and return us to barbarism does not faze our anarcho-communists and other exponents of the new "counter-culture." But what they do not seem to realize is that the result of this return to primitivism would be starvation and death for nearly all of mankind and a grinding subsistence for the ones remaining.

If they have their way, they will find that it is difficult indeed to be jolly and "unrepressed" while starving to death. All this brings us back to the wisdom of the great Spanish philosopher Ortega y Gasset:

In the disturbances caused by scarcity of food, the mob goes in search of bread, and the means it employs is generally to wreck the bakeries. This may serve as a symbol of the attitude adopted, on a greater and more complicated scale, by the masses of today towards the civilization by which they are supported … Civilization is not "just here," it is not self-supporting.

It is artificial … if you want to make use of the advantages of civilization, but are not prepared to concern yourself with the upholding of civilization — you are done. In a trice you find yourself left without civilization. Just a slip, and when you look, everything has vanished into air. The primitive forest appears in its native state, just as if curtains covering pure Nature had been drawn back. The jungle is always primitive and vice versa, everything primitive is mere jungle. (José Ortega y Gasset, The Revolt of the Masses, New York: W.W. Norton, 1932, p. 97.)
