Exactly blockchain doesn't servers any purpose if it used in a centralized way. What I would like to see is smart contracts being run on a public controlled blockchain. The governments are not ready to trust the people who are running the network, yet...
I think it is better if you will rephrase your last sentence in the quote as governments not being ready for reform yet since they don't want to part with their corrupted voting system and is not ready for honest, manipulation free election. IMO, the thing you would like to see would not probably come to pass unless someone will decide to work for its implementation.
