> What you're saying is we should allow kids to buy tobacco, to gamble, to purchase Meth and Heroine because Kids get around restrictions anyway

This is false equivalence. All of the above are vices that objectively carry more harm than good. There's no inherent harm in using a computer, there's a subset of ways in which using a computer can be harmful, which kids can be taught how to avoid or navigate, there's no subset of meth use that isn't harmful
