> Kids do all of this stuff anyways, making it illegal doesn't stop it from happening.
This so completely untrue! These things are absolutely effective for the majority of kids. Just because some stand out in a crowd, doesn't mean others are doing it too.
When trying to prevent something, the more friction you add the better.
Why do you want to add friction to teens having a creativity tool that can help them learn and build things?
I don't know what kind of kid you were, but as a kid I would have loved access to my own 24/7 polymath, it would have been an incredibly positive thing in my life. I often think of how much more cool stuff I would have accomplished with that ability. It would have actually benefited my mental health issues a lot, which often rotated around the boredom of living an isolated life in the suburbs and my imagination being unable to keep up with my free time and abilities.
If you add friction to good things in addition to bad things, you're just increasing the likelihood that the bad things will be chosen more often. You're also increasing the chances that people will not trust you when you say the actually bad things are bad, because you lied to them about the other thing so maybe you're lying to them about all of it?
