When buying alcohol in a physical store, in the UK we have the "Challenge 21/25" schemes https://www.drinkaware.co.uk/facts/information-about-alcohol... such that yes if you look very young the cashier/automated checkout assistant will ask for your ID but in most cases, they will approve without checking anything. I do not see any positives to requiring identification for all transactions.

It is not about requiring ID for all transactions, it is about when ID is actually asked for (which may not be every time), the information can be provided in a more privacy-friendly way.
