Banning Things for Other People Is Easy

An analogy would be that social media consumed by children is surely less harmful when it's a parent holding their own phone towards a child to show them a few selected photos from their Instagram feed. I doubt most people would object to that, even those that want to ban social media from children.

By that token, I honestly think we should ban more things that we know don't have an upside, and only have downsides, and the people who partake are generally doing so because of mental / physical shortcomings. In other words, if we know a reasonable person would not want to partake in a behavior unless due to manipulation and weakness, then I feel protecting that person is a kindness.

I myself have suffered from addictions that I can't seem to easily "choose to stop" even though I constantly wish I could. I really wish I wouldn't have been exposed to these things when I was younger and thought it was just fun. If I could, I would pay to go back and prevent my younger self from ever trying it -- because I had no way to know. And then I am a bit astonished none of the adults had that kind of concern. Sure a few people said "that stuff isn't good", but ultimately that lost to all the other factors (constant propaganda, ads, peer pressure, convenience, taste, addictive qualities, cost). It was never a "free choice" because there was huge information and power imbalance at play, and the "responsible adults" who could help did nothing.

You seem to be setting the bar at “if anyone violates the law then the law is a failure and should be revoked.” But that’s why we have court systems. They don’t just determine if someone broke the law, but also what to do when people inevitably do. You’re operating in a world where the only restrictive laws we should have are ones where it eradicates certain behaviors 100%.

You’re basically arguing against having laws rather than the merits of the law and its efficacy. Also “drinking like a a fish” when you were a kid was terrible for your development even if you turned out ok. Many people do not. It’s not even debatable, we know the numbers on this.

Late 90s... specifically after 1997 and early 2000s. But the anti-smoking campaigns before that were not effective. In fact, educating teens and adults on the dangers of smoking increased smoking. Smoking rates for teens peaked at 37% in 1997. it wasn't until the "Truth" campaigns where they focused on how the tobacco industry was basically a conspiracy, that smoking rates began to fall. And you can't pretend that tobacco taxes didn't play a part in reducing usage either.
