This is not so. Blockchain technology is an essential step to real democracy. Of course the government would be against it, but it all depends on people. For example, based on the blockchain, you can build a system of elections and recall of politicians. And much more.
The blockchain technology is a very innovative one and can have many applications. In fact, there are now many governments or regimes that are looking at blockchain to improve their services to the people and yes one day they can be adopting blockchain to improve transparency with elections.
For all we know, one day it would actually be the government which will lead in the application of the blockchain technology especially if the people would be demanding more accountability and transparency. Blockchain is available to all government or not government.
