The dystopia I see in your words: government as an efficient service provider providing for and competing for the patronage of the ultra-wealthy holders of cryptocurrency: the monopoly on force is broken because wealth is forever exempt. Socialized, societal wealth of all forms - roads, healthcare, police, defense - discarded. The underclass of every nation left without recourse to the power of government to redistribute wealth, and a global oligarchy is ascendant.
Government's first calling should not be efficiency. That's a misapprehension of its purposes.
