Instead of using libertarian meme-websites, I use an actual dictionary.
https://www.merriam-webster.com/dictionary/communism

a system in which goods are owned in common and are available to all as needed

Wikipedia has a good one too
https://en.wikipedia.org/wiki/Communism

is a philosophical, social, political, and economic ideology and movement whose ultimate goal is the establishment of a communist society, which is a socioeconomic order structured upon the ideas of common ownership of the means of production and the absence of social classes, money,[3][4] and the state.[5][6]

As you can see, communism has nothing to do with the state, it's just some states adopt some communist policies or strive to do so. States inherently have accountability problems and always need to be checked for abuse of power.

But keep clinging to the only "definitions" you can find that uphold your narrative.
