Experience has shown that prohibitions are ineffective. Kids will always find ways to circumvent them. It is therefore preferable to invest in education rather than attempting to enforce restrictions, IMHO.

Agree, kids always find ways, but denormalizing "unwanted" behavior (again gambling, alcohol, sustainability) can help awareness, if you will, with parents which they bring over to their children. It is not a holy grail, that does not exist, but it contributes, like education to what, as a society, we find acceptable and unacceptable behavior.
