except obvious bugs like the 2010 int overflow where someone created X billion illegitimate bitcoinsQED. Also see the recent Bitcoin cash fork, and the severe volatility caused by the speculation in the currency, which is a problem for anyone holding it.
A Bitcoin warpwallet, not so much.
I disagree. If it lives on a server a warrant will force them to give it up, if it lives on your computer, a warrant will force you to give the physical computer up (which can then be destroyed or kept indefinitely). It is thus as trivial to seize as the places it is stored, and as your physical being is (pretty trivial).
No I don't assume that. I had more in mind the example of a user wanting to donate to wikileaks, and credit card companies deciding to block these transactions. Bitcoin prevents this from happening.
I agree it was useful for that, but mainly because laws have not caught up with reality. If this were a widespread problem there are of course lots of avenues governments could use to shut off the funds, not least simply outlawing bitcoin, wikileaks, or both. I'm not saying that to be pedantic, but to point out that you're using technology to solve a social/legal problem. It may work for a while if it is not widespread, but laws are enforceable even against unbeatable cryptography because everyone lives in physical space.
If you want true change in your relationship to government, bitcoin won't get you there, because though it seems superficially useful for avoiding government scrutiny, it doesn't address the fundamental problems with it.
