Your friends are just poking fun, of course it's a real library. I also have a large number of ebooks (in addition to a 1-2k book physical library) and the ebooks are, paradoxically, less accessible. It's too easy to just download hundreds of books in one go (let's say if you wanted all the original Goosebumps books) and not actually look at them, whereas every physical book has to be obtained and shelved individually. Then ebooks disappear into Calibre where I utterly forget about them, whereas a physical book's presence on the shelf is a constant reminder that it exists and is waiting for me to read it.
