You act as if it's been tried any amount of time that would be statistically significant. Sometimes it's not even communism other than in name and folks still count it.
And it doesn't devolve into it. It's simply always been done at the same time. When you have essentially a dictatorship, absolute power will corrupt absolutely.
A practical distinction historically speaking, but not philosophically speaking. If you're unable to differentiate between concepts in history, I don't know how you can ever effectively discuss them objectively. Though, this should have been evident with your comment initially. Communism doesn't devolve into authoritarianism. They're not even the same types of philosophies. One is about governing and one is about commerce. It's like claiming capitalism devolves into a plutocracy. It does help to produce a plutocracy, but it didn't devolve into one. They're not the same thing.
This is a ridiculous analogy. It's also to the point of technically arguing one side while sarcastically supporting the other.
And it also ignores my actual point and sets up a straw man anyway. All you're doing is trying to claim I'm making a no true Scotsman fallacy. I am not. I never said every case of communism wasn't communism. I even implicitly stated otherwise by saying communism hasn't been attempted that many times for a statistical significant trend. I stated the failures mentioned were do to other problems. I'm not even claiming communism can or can't work. Just that the arguments provided don't support the conclusion. Being quippy doesn't give a free pass to avoid using logic and reason. I've even made comments against people making bad arguments in support of communism. I just want to see real discussions about it and not folks repeating sound bites from their favorite talking heads.
