Any part.

* We could get rid of all our technology and do pre-history style communism where people just work together to survive and thrive.

* We could do Chinese style communism where we starve Nazis by starving humanity by culling crops by culling sparrows with weapons.

* We could do Russian style communism where we cull Nazis with weapons and starve ourselves.

* We could do a form of bot-powered communism where chat bots tell people what to do, and people tell little robots what to do, and people who spend time and energy starting shit over factory ownership look increasingly dumb, and everyone actually is increasingly dumb.

* We could do another form of bot-powered communism where people tell little robots what to do, without listening too much to chat bots.

* We could develop robot arms, and then get rid of everything but our robot arms, and do pre-history style communism with everyone having 1 robot arm and 1 regular arm.

* Large armies could just disband, and people could just stop listening to dumb shit like "use money" and "work at the state prison" and "follow the new restrictions some people in Washington DC just came up with," and we could just have smaller groups and individuals with their own sovereign authority like the pre-history days, but without getting rid of modern technology.

The "anarcho" part is flexible if there's enough "communism" and vice versa
