Your scenario is like 10-20 years out of date.
Actual scenario: You are a kid with a phone or computer, you download one of the literally thousands of wildly popular free to play games on your device like Fortnite, and you begin playing immediately.
With F2P there is no payment barrier, which is why this sort of thing is coming up now. The constituency asking for it is parents who are having a difficult time telling their kid that they can’t be playing the popular thing that all their friends are playing.
Whether you agree with this approach or not is a separate issue, I’m not saying this is a good thing or well thought out. But the scenario and motivation are clear. The various industry rating systems worked when that was the only way to release a game, not so much when the most popular and high budget games are free.
Two things:
This is the EU, not the US. The forces you’re talking about don’t have nearly as much power there, American tech companies hate EU regulation and if they had as much power there as you presume, they would have killed DMA or GDPR first.
You might try actually talking to a parent trying to raise kids in this day and age before dismissing my comment out of hand. I assure you the demographic I’m talking about absolutely does exist.
