TBH, age verification services exist.
If it becomes law, integrating them shouldn't be more difficult than integrating a OIDC login. So everyone should be able to do it.
Depending on these services, you might not even need to give a name, or, because they are separate entities, don't give your name to the platform using them.
Other parts of regulation are more difficult. Like these "upload filters" that need to figure out if something shared via a service is violating any copyright before it is made available.
Also true in many cases in Europe.
You can get a flight ticket for under 20€ between Germany and UK (RyanAir), and have to pay tenfold that for a train ticket.
Or a 30€ ticket to Romania per plane. Booking a train to Romania is much more difficult and expensive and also easily over 100€.
I would wish that train tickets are cheaper than plane tickets, but if you cross country borders, booking train tickets becomes expensive and difficult in Europe.
