you are writing this as if you were never a kid yourself... there is absolutely nothing I wasn't able to "get" as a kid - some stuff I had to jump through some hoops but end-result would always end up being the same. if I wanted to watch hardcore porn, there was a way, if I wanted to smoke a cigarette, there was a way. if I wanted to drink, there was a way. and make it "forbidden" made it ever more appealing for me to get it as a kid. I grew up in society where alcohol was not a big deal, I was buying alcohol for my parents when I was 6-years old, would get sent to the store to get stuff and among the stuff was always beer and sometimes wine if my parents were expecting some guests. most of my friends growing up never thought of alcohol as something cool, we had easy access to it so it was like a rights of passage or anything like that and it showed, just about no one was doing any drinking while we were teenagers. when I came to america junior year of high school I was stunned at home much effort my schoolmates were making to acquire alcohol - could not really understand what the big deal is until I realized that was because it was forbidden and acquiring beer etc for a friday evening chill made one a cool kid.
the only barrier I have ever had to doing stupid things was the wrath of my parents. the punishment(s) levied when I did stupid shit was always such that I would very seldom-to-never-again consider doing whatever stupid shit I did. it always starts and ends with parents. you can put in whatever "laws" you want (which will always get weaponized politically at some point either immediately or at a later time) but end of the day the buck starts and stops with parents...
