Yes, some kids will find a way. I would have. But I have no problem making the barrier to entry higher, at least until parents start responsibly introducing their kids to alcohol or drugs instead of just pretending they don't exist or worse, arguing they are awful from a religious or otherwise zealous perspective.

In a perfect world, parents would teach their kids about how to party responsibly, but we don't live in a perfect world. At the very least, when kids get older they can arguably make slightly better decisions (e.g. think more clearly) sometimes.
