Is the problem that governments have too much power, or that they place what power they do have in the service of the rentiers instead of the people? The more power you take away from government, the more government-like power corporations themselves will wield directly. What kind of world will it be when all essential services are provided - or withheld - at the whim of the already powerful? When environmental or workplace regulation are replaced by courts, and the courts themselves are "arbitration services" run by the very same people you're suing, backed by security services run likewise? When the unprofitable or unpopular become "outlaws" in the very real sense of being denied basic services or protections afforded to the more compliant?
No, that dystopia - not a coincidence that so many SF writers have predicted it - is not the direction we should go. Governments have a responsibility to represent the people collectively where the people can not represent themselves individually. True liberty requires that tension between people-via-government and other kinds of power. It's awful that the government we have is pulling on the wrong end of the rope, but saying they should drop it entirely is practically the same. They should be pulling on our side.
This "make government tiny" philosophy leads to oligarchy and neo-feudalism as sure as Soviet communism did, for much the same reason. It's just another tactic that the autocratically minded use to weaken or discredit their potentially most effective adversary. What we need is a robust government willing to stand up to the oligarchs, not kowtow to them.
