Dismantling statehood, including the orgs that keep Cuba alive like the Cuban revolutionary armed forces, is exactly what the US wants them to do. Your proposals are the exact same as the US, their primary enemies who want to see them fall.
No it's not. 
wants far more than merely dismantling the centralized state.
wants total, complete, permanent submission, to rape the Cubans for their wealth, perpetual enslavement and genocide. I advocate decentralization so that the Cuban people have the best chance of defending themselves from these exact US demands. And I absolutely do not want Cuba to disarm at all; I want to see them stay armed and able to defend themselves against the
oppressors. But that doesn't mean I have to turn a blind eye to all the other forms of domination and non-horizontalness that the Cuban state, as a state, allows to develop.
Must be very important to Cuba to have the support of western anarchists.
... Are you insinuating I shouldn't support liberation for the Cuban people from imperialism, uncritically for the people of Cuba and critically for the state that lords over them? Like why are you trying to make an enemy to the Cuban people out of me? Seems like a silly move on your part.
Not capitulating to your bullshit-ass campist framing. Thought you fucking knew better.
