In another forum where I post, the bitcoin is seen as a threat to the working class.
Economic illiteracy is a widespread problem.
It's the working classes and the poor that mainly benefit from taxes in the west (well, theoretically) and for any economy the gobernment is Customer #1, so government spending of tax revenues pay for alot of the jobs in an economy. If people start turning stuff over in BTC then this starves the government of funds and they will no longer be able to provide public goods like schools and sidewalks and traffic lights, in the UK they will no longer be able to pay nurses and doctors or send dole-money or money for unemployed single mothers of small children. For me this is a bad thing.
For almost everyone, government is itself a bad thing. You just don't comprehend how much is taken from you in your "best interests". The most important tax that bitcoin deals with is the inflation tax, as inflation is functionally a hidden tax upon the entire monetary base. It's particularly regressive as well, most directly affecting those who save directly in currency denominated investments and those who are dependent upon a regular salary (i.e. working class) while most directly benefiting those with the greatest access to new currency (i.e. government, politicos & bankers). Bitcoin isn't really intended as a means to evade the kind of taxes that actually pay for public services, which don't have to be provided by governments in order to be effective.
Another thing about bitcoin is the indterest rate can't be controlled, I know this is a key feature, but isn't that something you need to be able to do?
No, of course not. Wow, you have been indoctrinated well. Did you attend a government school?
Assuming that you're some sort of democratically elected body accountable to the people, you might want to be aqble to accelerate or break the economy every now and then when it's over-heating or to ecourage it to move around more... Ireland could't raizer their interest rates and they came off the road due to the reckless DUI of their banks... and having no breaks.
The business cycle doesn't require intervention, and historicly intervention has proven counter-productive. The great depression in the US is a prime example of this, for it was primarily intervention that prolonged the pain.
