OK, let’s address what’s really going on here.
The OP wants to prove that the US is uniquely “obsessed” with requiring people to show identification. That there is something specific in US legal and cultural spheres that causes this.
The most frequent time a person is asked for ID is when making a purchase with a credit card, or, of course, a check. This has nothing to do with law enforcement. A person may be asked for ID in the course of a fiduciary transaction. These are measures designed to prevent fraud, and most if not all people welcome them, since the consumer is the one being protected. This is far from unique to the US.
Policemen will ask for ID on the premise that an honest, law-abiding person would have no problem with showing identification. The local law and the situation may or may not allow the person so asked to refuse. Again, not unique to the US at all.
For what it’s worth, I felt I practically had to glue my passport to my forehead in Europe, but when traveling in the US, I was only asked for ID when I wanted to check into a motel room.
