You’re appealing to definitions as if they matter in real world contexts.

If I created a group called “the bad people killers” and started killing people would that “by definition” mean everyone I killed was bad?

Communism may be defined as a wheelbarrow full of monkeys for all that matters, in the real world every self-sufficient communist regime was a shitshow of state capitalism, coercion, censorship, and state violence. All the drawbacks of capitalism and none of the perks.

That’s what communism, descriptively, is. The day you figure out a way to manifest reality by sheer will alone without having to deal with the real world I will be interested in what something is “by definition”
