They’re saying society is set up and engrained in a way where the best solutions for you and I are only as good as torturing ourselves with alarms and keeping a steady supply of frozen convenience fees.
They’re saying it’s only a “disorder” in a negative sense because society has failed to understand that the way things “work” and the traditional ways heavily favor the A-type extroverted morning people (sociopaths) who cannot comprehend how their routines might not be universal. Everyone is forced to live with it regardless because banking hours and business meetings exist for them.
You’re complaining about the very thing he’s saying is forcing you to be “disordered”
