I mean, communism has a particular definition, so if that definition isn't met, then it's not communism. Communism is a classless society with worker control of the means of production.
A sprawling centralized state bureaucracy is none of those things. Indeed, the whole departure of Leninism from Marxism is the idea of a vanguard party transitioning from capitalism to communism via a state apparatus. It's a fundamentally elitist doctrine that quite obviously did not work the way it was presupposed to work.
It's not like people don't talk about capitalism in heavily idealized terms, either. I've never seen an exegesis of liberalism that doesn't elide the pervasive and frequent expropriation and violent enforcement required to prevent the system from falling over.
