Communists never aspired to be structureless, definitely not in the short term. Even utopia they promised in long term had element of forced conformity with system aka oppression. Path towards that utopia was supposed to go through strong party discipline and obeisance. That is how communist party survived oppression in Russia.
It was not supposed to be "free" or "structureless" in any current meaning of the word.
I now much less about French revolution, but what I know suggests it was very complicated event. Describing it as simple attempt to move towards structureless society is simplifying it too much.
