> Didn't regulating cigarettes kind of work?
I am not sure what time or country you are talking about but when I grew up (Germany in the 90s) we officially could only buy cigarettes from age 16 (or 18?) and 50% of my friends smoked. So that did absolutely nothing.
Later (I think, man it's been a while) the vending machines needed a driver's license or id to verify the age and guess what, as long as you had access to a single person over the age of 18 you could still get cigarettes.
Stepping away from the cigarette topic... I think mixing the two topics does not make sense.
First one is: Is there stuff on the internet that kids should not be exposed to without supervision? I don't have a strong opinion, I don't have kids. Probably not, but I am not even interested in discussing this
Second one is: Will some stupid laws like the mentioned ones help in any way? Maybe a little, probably not really and only for kids who don't find a workaround. Will they have catastrophic side effects and thus are not worth implementing for minimal gain? 100% yes.
