No, they don't. There is no technological or cryptographic answer to the state's monopoly on legitimate force, its duty to execute the law, or any of its other functions that create and maintain the business environment.
It occurs to me that much of what crypto-lovers want is actually radically undemocratic. Vestigial states that can't do the bidding of the electorate because they're unable to hold companies to account and so on. People of this inclination are the death throes of the globalist dream: it is a fine thing indeed that the nation state looks to be reasserting itself in the face of one of California's more embarrassing wet dreams.
