Actually I'll apologize a bit. My tired mind apparently was a little slow to pick up on the switch to political philosophy. Hence why I was a bit confused at the semantics. I'll happily admit that I'm outgunned in this field, mainly due to a complete lack of interest in philosophy in general.
So...yeah. Basically my only addition would be that this was a derail anyway. The problems of the Soviet Union were in their general brand of what they called communism (I do believe that the original founders really tried to start a government that would help the workers...it just sorta went off the tracks quickly) due to a fairly incompetent and corrupt state.
I will say that Gorbachev's plans would have never worked, since people tend to be once bitten twice shy. They were pretty much done with the "caring" government (I also think that the old guard might have done a coup if the state would have been stable enough to actually allow for the change...we'll never know though).

I will argue that the inherent issues with the Soviet Union do speak of a larger problem with communism though.
Your position seems to be twofold.
First that communism would basically be like a direct democracy (at least on a local level...if I'm understanding you correctly). This doesn't solve the problem. It assumes that one group of people will have perfect information.
As my last Econ teacher put it, no one knows everything, they haven't since Archimedes

. So...you need to let the market as a whole use it's little invisible hand to guide things efficiently. Money tends to work well too, since a little bit of money overrides one's irrational positions (proven in some unrelated Psych studies I've read up on).
Second, it's a little bit of a No True Scotsman fallacy that the Soviet Union wasn't a true communist system. The only failure seems to be a problem in human nature not being ready for a socialist system. You seem to be saying that human nature would just need to evolve much more...but that's really asking a lot.
Part of my frustration is misguided anger at the fools who think that things like "The Venus Project" will work just fine if people would just change. It is misguided though, so I apologize.
Either way, it's just a philosophical point so it's gets more leeway anyway. That's of course why I usually stay out of philosophy.
Hope that that makes sense.
