I do see government intervention before it goes that far and it will be the draconian kind. They cannot coexist since crypto cannot be centrally controlled , regulated or tracked due to cross chain interactions which are undetectable. I only see one path for them and that is waging war on crypto public chains. Long jail time for hosting or participating, extradition and global cooperation since not cooperating might as well be a declaration of war.
This is still very-very far from happening. In developed countries traditional banking system is used by overwhelming amount of population - I don't know statistics, but lets say it's 95%. Cryptocurrencies on the other hand are barely used by even 0.5%. Most of the interest comes from investors and traders. Average users would need some good reason to drop banks that served them well for generations and adopt crypto instead, while government will be resisting it with all the possible means. And significant part of population actually believes that government is good and necessary, because without it civilization will fall. So crypto revolution is in my opinion only possible with political revolution that has a goal of reducing the influence of government in all fields.
