I'm not sure what you're even trying to say. This is about chronotypes and a teenager-specific sleeping pattern that has been identified and studied.
Sleep deprivation is torture, this is not my definition. Sorry, we, as a society, decided that not letting people sleep properly is really fucking crappy. If you want to disagree with that, take that up with the party that came up with the terms. Messing with someone's sleep is a major offense, and there are various ways in which it can happen, and psychology recognizes them, even if you don't.
Yes, I'm sure most teenagers have means to go to a sleep center, with their full human rights and disposable income. And when pretty much every teenager has this problem I'm sure that's a good use of resources.
