>> We don't bat an eye when a cop uses such tools to pull all of your license/insurance information during a traffic stop.

In order to legally drive we basically enter into a contract with the state agreeing to the terms it set. Keeping a current license, registration, insurance etc. During a traffic stop, it is a requirement to hand over the documents, if asked, so they can verify you are within the law. Atleast in the parts of the US that I am familiar with. Same for travel and other government documents, if you want to legally move between borders, you agree to their terms or stay put.

Having random creep take a pic of someone and get their address so they can visit later on, would be a very big problem.
