In the modern world, this is like saying people under 18 shouldn't have the freedom to be able to read and write. We would be decades back into digital stone age if we had held onto such a preposterous idea in the 80's and 90's. Virtually everything we have now is basically built by people who were hacking on their computers in elementary school and exercising their freedom of speech in terms of writing code freely at the discretion of their own imagination.
