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.
on point here. Blockchain technology is not all about currency, it offers a brand new technology that is feared by some politicians and bankers. From Email to currency to social media and other systems like agencies and programs ,blockchain technology can coexist there. This is a trillion worth technology and we must not underestimate this. Its true that some are taking advantage of it and making some promising overview of project but in the end what they really want is the money that's why they are making some shitcoins or a coin that is once a gold but left out alone by its supporters.
On the other side of the moon imagine a very big company like Microsoft Giant build a really big platform that is using the blockchain it would improve their system exponentially especially when they've created a coin that can be mine.
