Communism does not need to built up with a state either. A lot of communist thought points to the end goal of communism being the dissolution of the state entirely. I encourage you to do some more reading on the subject.

Damn you really want to show me your balls.
But yeah it's true, I just assumed we would be talking about the classical Marxist communism and not about communism as a spectrum, which it really is.
Not sure what you're going on about. The end stage of dialect materialiam - the root of "classical Marxist" communist theory, is the dissolution of the state.
You do need a commune for communism, but a commune doesn't have to be communist. If you study Karl Marx, he's very clear about that. He famously wrote about the Paris Commune aswell.
Communism is a political/ socioeconomic ideology, not a type of state.
