You are describing totalitarian authoritarianism, not communism.
This is why I felt that the distinction between communism and the failed USSR experiment was necessary. Sadly, whenever many people from the US hear the word communism, they immediately assume it means the Soviet Union. Communism was one of many aspects of USSR, many of which were much less desirable by its people.
Could you provide one example of communism that did not end up an authoritarian regime?
Communism is just not compatible with freedom. When free to choose, societies do not become communist, they embrace production and trade. You cannot achieve what communists want without extensive use of force
It has not been implemented on a state level without the state also being totalitarian. There have been few tries to do it on a state level, anyways.
However, on a town or district level:
1. Primitive Communism — basically all human history before the agricultural revolution.
2. The Paris Commune — Paris was run by its workers for a few months before bloody suppression by capitalists.
3. The Israeli Kibbutz movement.
4. The Zapatistas in Mexico.
5. The Rojava region in Syria.
Overall, there are many cases in which communism has been successful and sustainable for a long time at a district scale. In case of primitive communism, for thousands of years.
