These [0,1,2] are press opinions on her opposition to ID back then. The woman behind all that is far more interesting, but I can't find you more direct sources. She's a writer (fiction) too and may have expressed more in her autobiography or stories after coming out.

> Her own opinion was that ID cards would be of use "but only if they can be made unforgeable".

Internet identifiers with private keys are unforgeable unless the certificate authority is compromised, so seems like she would be in favor of this.

There is no disadvantage with this compared to just having a public identifier with no private part (current SSN scheme in USA).

> so seems like she would be in favor of this

No I don't think she would approve of any zealous solutionism. Not that I personally drink tea with her, but from what I've read SR occupies that class of intellect that deals in philosophical fundamentals of human affairs high above the 'technician' who says "Oh we've solved this with new fangled thing X now". And I'd bet my comfiest boots on some "certificate authority" being compromised before the ink is dry on this comment. I mean... look at what the title of this thread is about. :)
