The term was used to show how, through development, future structures “rhyme” with those in the past. Early communalism, as I prefer to call it, shares in common with communism classless, stateless, and moneyless society, but the key difference is the scale and the level of development of the productive forces. The sheer difference in what we use to produce what we need, and how we distribute it, makes these entirely distinct modes of production and distribution.
Communism has not existed yet, so I see no reason for you to believe it to be almost impossible to build.
Primitive communism existed for hundreds of thousands of years though.
