Agreed - bitcoins are just another financial tool, fundamentally agnostic about how they are used, but they have several anti-authoritarian properties that many ideologies should appreciate (or fear).
And speaking of ideologies:
WTF, Cato doesn't even accept bitcoins? And sure enough, they don't. This seems like such a no-brainer... perhaps EFF's lead set a precedent for Cato? Cato even published a half-assed article about bitcoin back in July. Any group like Cato with one of the Koch brothers on the board has deep enough pockets to fund a defense of bitcoin, unlike the EFF.
