I am by no means disagreeing. I am just saying there is an argument that could be made better. Asking a reason for traveling or verifying passports in absolutely nothing new and makes the point the user is trying to make seem disingenuous to a degree.

I don’t think you pointed out the reason why you care? Also some of those things are not anything new so are not at all supportive of the point you try to make.
