I think the metaphor Mr. Kint was using for how the online world needs to reflect the expectations and practices of the offline world is really important. We use the metaphor of privacy in the home as an interesting way of thinking about digital privacy. When you invite someone into your house, if it's a stranger, then you might not let them go beyond the entryway. Other people you might let into your kitchen, and other people you might let use your bathroom. Do you let anybody rifle through your bedside table drawer? No. Privacy is a continuum, and I think that continuum needs to be clarified for government services so that when citizens provide identity authentication, they understand it through an off-line-world metaphor.
Of course, government is different from the marketplace. Validating identity as a citizen is different from validating identity as a consumer.
