That said, I think requiring ID is generally a bad idea regardless. Much better would be some standardized way for websites to tag the type of content in a header coupled with third party filtering solutions that could be applied at the network (ie firewall) or device level.

What seem to lack is the will power to use them. Or after seeing in the linked site:
*EU politicians exempt themselves from this surveillance under "professional secrecy" rules. They get privacy. You and your family do not. Demand fairness.

RTA stands for "restricted to adults". So the large websites, ie the entities that would actually be bound by any proposed legislation, are already proactively facilitating network operators and parents filtering them out. And apparently have been all along. Wild.
What happens over and over only reinforces they idea that they really want "everyone, empty your pockets and show your papers, NOW!" laws and just hide it with "it's the only way, trust us; for the children!". A pretty telling proof is they want to be exempt.
