The solution is clearly to have a first revolution which establishes a socialist state and then a second revolution after the capitalist states have all been defeated. (I am only half-joking)
while i personally despise trotsky because his adventurism regarding his views on permanent revolution endangered the soviet union and communism as a whole, the concept itself is valid. the tree of liberty needs to be watered with the blood of patriots and tyrants from time to time after all, even if that quote specifically was made by a chud the sentiment is real. without the occasional violence in society to shake up the class structure, hereditary power and corruption will entrench itself into an utopian classless system given enough time and that endangers the project of communism as a whole, so we need purges, not reeducation, murder, the death penalty carried out on reactionaries basically until the end of time to maintain communism. communism is not pacifism, humans are innately violent and a utopian system would require it.
This is a ridiculous take. A classless system does not endanger communism, it is communism. Reactionaries are not timeless, they are explicitly contextual. Humans are not innately violent, physics is. Violence is useful in accumulation due to scarcity and social structures. Getting to classlessness and moving beyond scarcity will create incentive conditions that make violence less and less viable as a means to accumulation until ultimately everyone will be fully enmeshed in interests that align with peace over war.
