It's not about banning design patterns. It's about removing the harmful results they produce.
Can you imagine if gambling were allowed to be marketed to children? Especially things like slot machines. We absolutely limit the reach of those "design patterns".
And that's because they're much more responsible with alcohol. Americans get introduced to alcohol as a rebellion from oppression the moment they go to college. Germans have it with dinner with their parents sometimes when they're 12. It's like how Facebook got boring when your parents were on it.
I don't get that impression from Europeans. Also I've had wine at home since I was 12, but still ended up getting completely wasted the first time I had alcohol in college. Pretty sure anyone who's interested in that will do it at some point, and that's the only way to outgrow it.
Anecdata, but I don't remember my high school friends in Europe being much more (if at all) responsible with alcohol than my US friends were when I went to college there.
They just started getting blackout drunk 3 years earlier.
