The "privacy from governments & banks" bit will probably alienate a hundred times as many people as it would attract.
I disagree. I think if you do a poll
"Do you trust the govt?" it would only be slightly lower than the results for "Do you trust the banks?".
i trust the banks more because i have a specific written contract with them. maybe stupid.
but i have no such contract with the gummit so it seems they can get away with far more abuse.
