See - I think this is the root of the issue.

As technology has evolved it has placed much more power in the hands of centralized power.  Either power that comes with wealth (avoid offshore taxes, hire lawyers, etc) or power that comes with actually being in power (NSA wire tapping, etc).

I watched a really good video by Gavin Wood who essentially said the idea of anonymity and privacy is not an "is" "is not" issue.  It's about making it cost prohibitive enough that the government is forced to pick their targets.  Not throw a blanket over an entire population.

I think the ancap is a completely failed idea.  As is libertarian (they are different).  Just look at the altcoin ann section.  THAT is ancap at it's finest.

I also feel democracy has failed.  So I'm not really sure where that leaves me.  But anyway.  I agree with you that the ethics of total anonymity are tricky.  But I think I lean towards the blockchain providing anonymity for all in the protocol to *try* to insulate the individual from the centralized powers that be.  This helps continue to level the playing fireld between the rich and the poor at the same time as far as functionality / what's available to them
