Must 24 Hour Fitness be open all the time?

It is convenient that you don't have to worry about when the gym is open but in a world where systems are created to prevent unwise decisions why does a company promote an insanity that is an always open gym. Here is my reasoning:

1) Cortisol the stress hormone is not optimized and really screws with you when you workout during unearthly hours.  No you are not special and be one of those people who are more productive at night ... just go to sleep when dark, awake by day.

2) If you can't find time to work out during the first 20 hours of the day it speaks to a shortcoming in the planning skills and priorites.
