I'll put it in my terms.
I think the Estonian model is interesting in that the risk of digitized government services based on a common digital identifier, in the worst-case scenario, would be that the government, whether only the federal government or governments generally, would have a single profile of that individual. That is, of course, very difficult to reconcile with privacy.
One of the apparent virtues of the Estonian model is that the data is not centralized. It continues to reside in a large number of institutions, and there's a technological pathway with appropriate legal authority authorizing the information to be reused from one department to another. The decentralized aspect of the Estonian model, I think, at first blush, seems a positive feature that reduces what would otherwise be a risk.
You mentioned concerns that were expressed.
