> School libraries serve so many other roles: meeting spaces, learning commons, exploration/maker spaces, and just a safe space for students.

This is really the point I'm making. Those 'other roles' are not inherently linked to the 'library' function. It's just that as libraries themselves declined in utility, the space was re-purposed to fill those roles. But there is no reason you can't fulfill those functions without the 'library' part - and, indeed, this is increasingly what you see on college campuses.
