I appreciate your deep dive into these scholastic studies. I always appreciate learning new things.
When an idea has resulted in the deaths of a significant portion of the world's population at the time, it's healthy to regard it (and similar ideas) with a bit of skepticism.
I'm specifically trying to avoid the whole "no true Scottsman" argument by saying these aren't necessarily examples of how an actually functional communism economy would be, but I do wish you could be consistent with your terminology as socialism and communism are distinctly different ideas. I'd also like to emphasize the mild sarcasm when I used words such as "merely" and "complete and total cooperation",to close out this conversation which I have little more to contribute to.
"If only every single person would..." is not how you create policy where people are actually free.
