They certainly don't work for me. I have to pay something between 20-80% of all my income and financial gains to governments despite the fact I don't agree with anything they do, or with their existence. I never signed a contract with them agreeing on that sort of taxation, and if I don't pay the taxes the government imposes on me I can have my property taken away from me, get arrested and even be assassinated. I als…
And who prevents the criminal or military leaders from taking over once the governments fail in your scenario? Are you saying there won't be anyone around who attempts to seize power? That isn't how things have played out in areas of the world where central governments have failed. The more likely scenario is that we're headed toward a world state. That's the direction civilization has been heading since nation state…
There's this idea that "because things have been playing out in a way, they'll keep being played out this way", despite the fact the increased means of production (call it "technology") change things fundamentally all the time.
It's very expensive to maintain the military. It's only possible nowadays as governments can impose taxation and due to the currency monopoly they can print as much money as they want to fund that sort of self-preserving activity, which is technically called "debt spending".
As decentralization spreads over, the management costs of taxation skyrocket, and the currency monopoly disappears. Without that governments can't fund their own activities. Which means they'll shrink progressively. As time goes by, they'll start failing at providing law and order, and private companies start providing protection, insurance and private arbitration services to people. Further down the road those companies in their aggregate will start protecting people from the state itself. The state then either becomes a company which some people voluntarily contract services from, or it vanishes.
I'm pretty sure someone would say that the "evil companies" would then merge and become another government, but that's only if that person missed the whole point: in the long term centralization is not economically viable, and in a non-regulated free market environment monopolies are not really possible. As those companies are voluntarily contracted by people, an attempt to fight their customers would be catastrophic as they'd unrecoverably lose their business to competitors.
