I love natural light and get as much as I can when I'm awake, but it's not required in my bedroom, especially if alternative options are a long commute, sharing a room with a stranger, or going deeper into debt. To me it's crazy that you would choose a 45 minute commute over a small and/or windowless room in college, but I understand people have different priorities; I'm sure there will be at least 4,500 students that will appreciate and choose the option to live alone, cheaper, and have the other amenities in exchange for a window. There's no need for outraged outsiders to pre-make that decision for them.
And, incidentally, I don’t need to accept the challenge to block my windows. I already have blackout curtains that I never open because the only time I’m in my bedroom is when I'm asleep or it’s too bright/hot to open. And I can’t use the natural light to wake up since where I live sunrise varies from about 4:00 to 6:30am, which doesn't work with my schedule at all. I've considered buying an automatic curtain opener to make use of the light as an alarm, but haven't gotten around to it, so for now the curtains just stay closed.
