So is the solution to stop prescribing medication to everybody because there are stupid people who DO NOT FOLLOW THE PRESCRIPTIONS?
The art of statist is to oppose controls on everyone in the name of those who might actually need the help of the government.
That is what, "it's for the kids" is all about. We as a society assume that children are incapable of taking care of themselves and therefore someone or something must interpose itself and control their lives. If you go under the ghetto and find children who can't read and teenagers shooting each other dead in drug wars, the statist has all the excuse he needs to step in and legislate or regulate. These are extreme examples, but statist do it when they oppose homeschooling and we do it across the board once we have raised the justification of "for the children."
Liberalism seeks out the eccentric to justify control over the normal.
