Sometimes, when I make comments on websites, I say to myself, “I’m probably over-reacting,” but in this case, I don’t think I am. You say, in your video, that the user can “provide this data — if they want.”
I think it’s important to recognize that when a system (no matter how safely encrypted) carries immutable, unfakable data about identity, that there are people who will use even the existence of that information to their advantage and to the disadvantage of the individual.
Please do me, and future generations, a favor and read this article: https://medium.com/@tjayrush/be-careful-little-brain-what-you-code-6ad4d5fb9d9b. In it, I try to make the point that these new identity systems, while being amazing, may have profoundly negative unintended consequences.
How does a father who’s run afoul of an evil regime “provide data — if they want” when some border guard has a gun against his child’s head? Especially when saying, “I don’t have my identity” is obviously false because he has his phone?
