The link you provided basically describes finding such a system appalling yet you seem to advocate for it. Somewhere in our sparse interactions I assumed that you were an anarchist. Perhaps I was wrong in that assumption. 

My biggest issue with communism is that its proponents tend to have a propensity to implementing it through the creation of an all powerful and violent state. They sell it in the same manner of this book as if all people will just automatically fall in line with it and be happy. Reality tells us that it doesn't happen like that, at least not on a grand scale. I'd say even on a small scale, it is every bit as susceptible to the evils of man as is capitalism.
