The difference you barely have to show you physical ID - mostly only when interacting with bank, signing document, government. I never got asked when buying alcohol and if asked at least I would only let to have a look instead of snapping a picture.
Imagine if suddenly every grocery, pharmacy, petrol station, parking place, restaurant, bar etc. now would ask you for your ID AND would snap a picture and store in their database - you wouldn't be happy about it.
