I agree with you that we can let people decide what trade offs they value; however, there is an issue where the university could find out that this is harmful to mental health or simply that students aren't willing to make this trade off. Now you have this giant building that isn't being optimally used and it could be expensive/difficult to repurpose it. Also, I sleep with blackout curtains too! It's a much different experience than waking up in a pitch black room. Small slivers of light make it through the edges of the curtains and that makes a HUGE difference in my own experience. Even in the winter when it's dark in the morning is a different experience than the pure pitch black. I know what I'm describing sounds silly and ridiculous but it's hard to explain how unsettling it is to wake up in a room like that.
