I think it's fair to call all attempts so far "not reall communism". But you don't have to conclude "real communism would work". You can also conclude "real communism seems unimplementable". It is, after all, a social order that was created purely on paper and from theoretical arguments, which is ridiculous. That activity gives you something to try, but certainly not a fixed solution that you just need to implement as prescribed.
