"and the majority of passengers would be quite happy"
Maybe, but I think not. Even if you've not got a window seat, knowing the windows are there and that you can see a bit of blue through them almost certainly has a psychological effect. I suspect having no windows, or having to leave your seat to go to a special area that has a window would leave people feeling a bit more closed in. Possibly one of those psychological effects where you don't actually realise it's causing discomfort.
