The fact that governments own a lot of it is not the problem. There will always be rich and poor people. The problem is that money that doesn't exist is lent and people pay interest on this magic money, you can't do that with cryptocurrency. Counterfeiting is impossible with crypto and the biggest counterfeiters are governments.
For your theory that crypto will enslave us, I can't tell for sure, it may or may not. Crypto is the perfect tool to weaken nation states and further globalization but on the other hand you are not forced to use and there are more than 800 differents crypto to chose from so I'm not sure how they can control this.
