It will only take a tax office a rather short amount of time to come up with a way to tax you. People seem to think that Bitcoin means we can get away without paying taxes, only because it seems to circumvent the traceability of money. In reality the government has unlimited power and creativity with which to tax. They would just come up with something else to get their revenue.
Might be as simple as taxing your connection to the internet, through which you run bitcoin. Or the electronic device you run Bitcoin on.
