Your concerns likely are legit and justified. It appears indeed what plenty of governments are already working on and pushing towards just that .. and it won't be pretty if they ever manage to convince enough people to make it a mandatory if not the only legitimate way of monetary exchange.

However, I think it's actually the current unregulated crypto currencies ecosystem that should worry people far more. Consider the shady people that operate this space and their ability to mine all kinds of data. People might be surprised how valuable and useful behavioral data of individuals can be, especially when it relates to how they behave when dealing with speculative and uncertain dynamics (like e.g. the realities of crypto currencies themselves). That's all I will say about it.
