It's a pity the article is so long, because otherwise you might have encountered this sentence before composing a reply:
It won't be enough to demand an early hour for going to bed. If you ban the late evening Internet surfing, you will just swap a dose of evening education for an idle tossing and turning in bed.
You can't necessarily change your biological clock by an effort of will, even if you know exactly what you are doing -- which few people do. Your biological clock has a "mind" of its own. No matter how much "responsibility" you take for your schedule, and how much intelligence and full-spectrum lighting you apply to the problem, you may find yourself unable to be optimally awake at 7am. Especially if you are a teenager.
Meanwhile, I'm afraid that everything about this reply rubs me the wrong way. It is a textbook example of its kind [1], and it illustrates why broken designs persist for decade upon decade. School day starts too early for the typical young person's biological clock? We survived it, so should you! Third-shift workers causing accidents at 3am? Your grandpa worked third shift and survived with 80% of his fingers intact; so should you! Medical interns forced to work continuous shifts of 24 hours or more, even though studies have shown that they therefore make avoidable errors that harm patients? We survived it, so should you!
It's so much easier to instruct the victim on coping techniques than it is to contemplate changing the system that it becomes a reflex: You poke an adult, and out pops a sanctimonious lecture.
