Enumerated columns only allow for one option. If I have both a physical copy and an eBook, I can't select both.

dummy.paperbook is a zero-byte file; there's only the record in the MFT.* My physical books make up only a small part of my library; making a separate user column (necessitating a new table or even
two of them in the database) and adding a value for
every book would likely be less efficient.
Also, a custom column can only be used inside Calibre; in the filesystem, I can query for the .paperbook files themselves to check their existence.
* When using NTFS, very small files (<1 KB I believe) also store their contents directly in the MFT rather than move them out to disk.
