The ability that the blockchain gives to economically coordinate across great spaces and at massive scale without a central authority may make Tim May's predictions come true.

"Crypto anarchy will alter completely the nature of government regulation, the ability to tax and control economic interactions, the ability to keep information secret, and will even alter the nature of trust and reputation." -Tim May, 1988

I would add that limiting the ability of the govermment to tax and control economic interactions does not imply eliminating the government's ability to collect taxes. It would instead mean governments shifting from taxing people's private transactions, which properly belong in the private sphere, to taxing immovable property within their jurisdictions, like land, which properly belongs in the public sphere.
