We've been needing this for a long time, primarily to regain control of the public schools, where various court rulings have found that unruly adolescents have virtually unlimited 1st and 4th Amendment rights (but mysteriously no 2nd Amendment rights).That would be one benefit. The right to home school would also be protected, and government meddling with kids outside the knowledge of their parents stopped.
In retrospect, I'd make a change to tne first section. I'd change "on the basis of age" to "for any reason without due process of law". While the Fourteenth Amendment is generally considered to place the restrictions of the Bill of Rights upon all levels of government, this would cement that protection.
