Bullshit.
Governments started already employing blockchain technologies and they will co-exist with the current economic system. Five miners in China are in control of 80% of all BTC transactions and important decisions. Who owns BTC? Well, take a look at at this;
Bitcoin is as centralized as any other government. Most coins are. A few people have the control. What is decentralized is the technology, NOT the system. Kind reminder also that if you are once in the blockchain then you are forever in the blockchain. When governments start employing this then nobody will be able to escape from the permanency of their transactions.
This pedantic obsession with the government won't serve anyone justice since the government is made up of people. Homo-sapiens with the same passions, greed and general behavior as in any country. Consensus is just another fancy word for democracy. Do you get a vote for Seqwit? Do you matter? Ofcourse not, much like in the regular world.
