Re: Identity is horrendously complicated though,
Yes. A secure dollar asserts "I am me and I'm worth a dollar, just as good as any other dollar." An identity assertion says "The person known uniquely as 'Yes Me' originated this data item or session." Those are very different assertions. The dollar is self-describing and self-contained. The identity assertion depends on some trusted third-party source of the ultimate truth about 'Yes Me'.
