I dunno! To be honest an authoritarian corporate regime seems scarier to me than an authoritarian state.
Atleast with our current governments (in western europe anyway) we have some kind of sense that they are providing us with basic securities. I'm not sure if corporations are even remotely as employee oriented as states are people oriented.
Take away the power from the state, it creates a vacuum. Who will fill it? Facebook? Google? Banking Corp X?
Seems to me like there may be some sense in having a state. They're not all bad. They do offer protection from perhaps even more evil things. I guess you could say the same about the italian mafia, though. In the end I guess it's a matter of which mafia you'd prefer to serve.
