You're acting like there are no wizarding libraries. There are, and they're better than the muggle ones in so many ways - for example, we can have more books in less space. Hover charms and such are marvellous things, don't you think?
But you say "I'm a huge proponent of muggle libraries" as if they're something new and innovative. They're not. They're merely substandard imitations of something wizards had already done, better.
This is the problem with this intermingling of cultures. Too many wizards act like what muggles have is somehow better, more useful, simpler, when the truth is that they're scrambling to find roundabout ways to do the things we do with magic. That doesn't make them better or more interesting than us.
Catch me dead driving one of those godawful automachines down a road surrounded by a hundred other automachines, stuck in a queue when I could just Floo somewhere, or Apparate. Catch me dead using a bloody magnowave to make food when I can wave my bloody wand at it.
