Why though? Not disagreeing per say because I'd have thought so too, but upon reflection...
I assume the main reason airlines require an ID is safety and security. We maintain a denied parties list and use identity verification to make it as difficult as possible to fly a plane into a crowded venue. Border control is another issue, but there's plenty of intra-country or intra-state flights where this isn't an issue.
Ticketmaster sells unverified access to crowded venues.
I'm also probably overly discounting border control. Traceability in particular. I'm not a fan of this either.

Practically, I don’t want Ticketmaster having access to the information on my ID, they already leaked lot of my other PII.
Can no longer pay cash, have a paper ticket, be anonymous. Those are much more important to me than preventing scalping.
Scalpers out front have provided a valuable service to me a dozen times over the years, when I didn’t plan well.
Any solution (I didn’t ask for) that turns concerts in an international flight experience means they are dead to me.
Age was traditionally checked separately and manually. Not put into a database to be bought and sold and breached.
I did not have an ID, and none was required to get in.
All-ages shows are definitely things that exist.
It's to my understanding mainly the US where ID requirements are often side eyed because many people don't have them and there's no national standard (and due to a variety of political reasons there probably won't ever be any.)
In the US, permanent residents are required to carry their green card at all times.
