Taxation is theft. Regardless of Roger's attitude towards Bitcoin, he is being hunted down by a government who wants to steal his wealth. My support goes out to him.
Yeah but it is legalized and widely accepted.
In ideal world taxes would be voluntary but let's face it, most people wouldn't pay it if that was the case.
Than comes the stupid question - but who would build the roads?

That's a common argument used by people who never actually looked at the situation and believe they need the government to "build the roads". The government merely pays the company with YOUR money to build the roads, not the government itself. Plus the private sector would be more efficient in planning, building and maintaining "the roads". It would probably be cheaper for the people too, although a new model would be needed.
