I think you severely, severely underestimate the power of the financial-governmental complex. As long as the kids are playing in the park, they'll let you do. Once you are threatening their lucrative business of pumping productivity of the economy in the hands of their elite, all means are good to kill you. Wars have been fought over much less.
You think the old-boys networks of banksters and government are going to let this happen ?
I think when this is the only arguments doubters can come up with then half of the battle is won. The fact is bitcoin is an internet protocol, they can only hope to slow it down for so long until the masses unanimously reject their worthless fiat.
The banksters have their own economic crisis to worry about anyway.
.... as long as the banks and mobsters allow you to !
I see you've ran out of attempts at reasonable argumentation. That's okay.
Most technology adoption didn't have a flame-throwing dragon the size of US government and the banking sector fighting for its privileges in front of him :-)
They are well on their way to lose this privilege by their own action so Bitcoin is the lubricant that will ease and hasten the transition.
