Yes, communism is yet to be ever implemented in reality, but i see no problem with mentally evaluating the idea before implementing it. After all, do you jump off the roof before looking down, or you look down before jumping? I’m sticking with the second one, and if you’re not, i suggest you call your local suicide prevention hotline.

Communism, no matter the flavor, will anyway be laying somewhere on a spectrum between centralization and decentralization, so it will be vulnerable in any case. If you can imagine an idea where it isn’t, i wholeheartedly ought you to share it.
