Your post that I replied to said that no governments wanted free energy, now you are shifting the goal post to some sort of further made up hypothetical world where big governments have free energy and small governments don't.
I reformulate: no governments that theoretically can achieve free energy want it, perhaps governments that can't dream it as a temporary solution to find a way to lock it out for their own sake. Better?
Keep in mind a thing: hitler was not blocked via military operation forces against forces nor interior civil war but due to the lack of gasoline. And that's true for essentially anything. If you can "ground" a country you can rule it to a certain extent a thing any government powerful enough want.
Did you remember prohibitionist in the USA to avoid an improbable development of alcohol powered cars because produce alcohol is easy, produce gasoline it's not?
