I think socialists should probably stay away from bitcoin if that is the case, namely due to how difficult it is to tax. Especially if people begin trading bitcoin over the tor network.
By investing in or even mining bitcoins, socialists would be contributing to the decline of socialism. You'd basically see a return to the early days of the US where they relied upon the taxes of sales of certain goods. Services would be unable to be taxed effectively, and income for large corporate entities would be hard to tax (which would be a good thing IMO as corporations as it is don't really pay any taxes - they just push the expense on to the customer.)
do you know that some people, actually wants to pay taxes because they supports the system?
You said you live in denmark earlier, correct? You know denmark is one of many countries who spends more than it brings in. It is dependent upon borrowing. Should there be a global deep economic recession, that system you support will collapse.
I don't know how likely denmark is to have a balanced budget any time soon, but france, england, the US, and japan are all heavy borrowers (Japan is by far the worst) and when that house of cards comes falling down (this is inevitable by the way, my guess is sometime between 8 and 30 years, and the world will place the blame squarely on whatever political party holds the US white house, even though it is a global problem.) Your social programs will collapse along with it. The reality is, we really can't afford to do these things, taxes or no taxes.
and there are many non-socialistic countries that have a way higher debt/GDP ratio, than Denmark. i think we are doing pretty good.
