I disagree, the fundamental issue with communism is in its design. You either let the government control your economy, in which case authoritarianism will leech those who toe the party line to the top and corrupt. Or, you design another system/group to handle economic concerns. In which case, they will simply turn into a government in all but name.
There’s a reason the state owned businesses of the fascist Nazis and the collectivist “public ownership” of the Soviet Union looked the same in practice, when in the realm of theory they couldn’t be more separate. Those in power (whoever they may be) when allowed to put people in positions of authority who they desire, will just put their favorite yes men there. Whether that’s a required backing of the nazi party/a bullet to the brain, or just being next in line because Lenin had your superior killed for failing to meet expectations. Authoritarianism is the rule of the day and they all exercise it equally.
The economy is best left to the needs of a market that has the appropriate organization and division of labor, land, and capital. It only self-destructs due to the misguided notion that wages are derived from capital instead of labor, and the justification of the capitalist at how much of the slice they deserve based on that misdirection.
