If I hold a gun to a taxi driver's head and compel him to drive me or anyone else around for free, that doesn't make me the provider of public transportation. The worker is still the one providing the service. The fact that some other psycho might do the same thing or worse is no reason for me to be doing it.

Bitcoin, if adopted fully, severely cripples the government's ability to exercise that kind of control. To use the US as an example, if they have 200,000 bitcoins, that's about $24 billion worth if BTC. But they spend about $6 trillion USD annually. There's no closing that gap. That represents trillions in wealth that gets released into the market's control if USD loses its social status.
