I agree. If bitcoins only purpose/advantage is as an inflation-hedge, there are numerous things that would serve that function. The major differentiator, in fact the only differentiator that will have a significant impact on economic growth and taxation policy, is bitcoin's potential for user-determined anonymity and untracability.

Yes. Because retaking our freedom and extending it globally is going to require breaking quite a few laws. Stop paying your taxes, stop filing paperwork with the Enemy. Stop participating in the Enemy's staged political show. Disconnect from their system. Remove your money from its banking system and store your savings in new forms of wealth. Develop a support network in the underground economy. The old system is disintegrating and a new one is growing in it's place. Your new life will be as freeman or slave, the choice is yours. Easier said than done? Sure. Better than life on your knees? I say yes.
