The "state" may be required.

[u/OkManufacturer8561]

Communism is a stateless, classless, moneyless, society, a utopia one may add. Unfortunately, I believe we may need the "state". Now, it ultimately depends on how one defines the "state", however if one of the key factors of the state is a military, police, armed forces, ect. I am here to state that we may require said forces to defend ourselves and expand our civilization against other species. This is unironic.

You are starting from a bad end and reaching the correct conclusion. Communism as you defined is defined that way by Marx and explicitly stated as NOT utopian. Communism is the movement to abolish the present state of things. Read German Ideology and Critique of the Gotha Program.

The State is only necessary because it is a product of class society. It will only be a thing such that there are classes. It withers away as classes cease to exist. Lenin goes over this in State & Revolution, but he also quotes Marx on this in his work the Civil War in France (and Critique of the Gotha Program).

The question still may beg though; what is the "state"?

I would strongly encourage you to read this free book: https://en.gegenstandpunkt.com/books/democratic-state, by the GegenStandpunkt (a German marxist magazine and publisher). They set themself apart from ML, MLM and so on and base their arguments solely on Das Kapital and Critique of the Gother Program. At least read the introduction and see if it sparks interest.

Edit: just so you know what the state is not: The state is not the political force of the capitalist class.
