I am lost. Why do credentials have to be centrally stored?

I don't believe in centralization of anything when dealing with privacy 
via verifiable identity. I don't think we are talking past one another, 
I think we have differing view points with regards to network topology 
and the implications on verifiable identity in a social context.

I am sure you could spell this out with some additional clarity if my 
position outlined above remains unclear.

I see privacy as self-calibration of one's vulnerability, in any realm.
