Actually disagree, at least not higher-stage Communism. Higher stage communism requires pretty much all living generations on Earth to have never known Capitalism, and be so used to living within Socialism that the statist apparatus makes itself redundant and whithers away. This becomes self-perpetuating and stable.

Lower stage communism? Absolutely.

It isn't simply a matter of "confronting internal biases," just like you would not place a random modern worker into feudalism and expect them to be capable of tending the fields, producing for subsistence plus surplus to their local feudal lord, and producing all manner of household goods such as clothing, fences, and food, so too can you not thrust the modern proletariat into a higher stage of production without working through the transitional status of Socialism.

If there are communists who think communism can be attained in our lifetimes, I don’t know them. We’re not going to sell people a fantasy, some overnight utopia. Some places are now socialist, and more may become so in our lifetimes. But, as socialist states themselves will tell you, communism has not yet been attained anywhere.

I want to live in the commune with nuclear arms. To many shitters in the world as it is.

Communism is not attainable in our lifetimes as it will require decades upon decades of economic and social development. But we can take the first steps by seizing control of the state from capital and oppressing the actions of capitalists themselves. In other words, by creating socialist (or proto-socialist) states.
