Parenting done right

It goes against reality. You will not find communism in nature. The food chain by its nature is not communist. Organisms eat each other for food, parasitize each other, use force to fight for territory, mates, food, etc. The watering hole on the savanah is peaceful and all the creatures share it until a lion gets hungry, or a hippo gets upset someone is standing too close. Until two male antelopes both see the same female in heat. Even insects who are often held as examples of communism- they have class, they have a queen they serve and they war against rivals of their kind over supplies. When there is enough for everyone to have whatever they want we don’t fight over what there is. When we live on a world with only so much space, so many beaches or “prime” real estate, where clean water, fuel, minerals, fertile land, are all limited- we will fight. It’s not human nature, it’s the nature of life. Organisms compete to survive.

First. You can still try to be an animal and do not try to become better. Your choice. Second. You even don't know what is communism. Communism is not about "human nature", it's about social equality (social, not rights) and equal rights to social property.

We as a species split the atom. Energy from matter. Enough to never go without. Why isn’t my car nuclear powered? The goal of the scientists chasing fission/fusion was this. But it became a weapon. A weapon these scientists built hoping for peace. The goal of a thing- a philosophy- a tool- all the same thing, all in the pursuit of “becoming better” is not important. Once it leaves the drawing board and people get involved human nature becomes a factor. You define communism in its lofty goals but don’t recognize capitalism is likewise meant to motivate and reward working for societies good. Humans use the tool for their purposes. Twist intent. How do you reconcile your statement that people can choose to remain as animals, with a system that requires everyone to participate in social ownership? What of those who wish to remain “animals” and cling to individual ownership? A “perfect” system is useless if people don’t use it.
