Considering the author already strips the DRM from the purchased e-books and also apparently knows about Z library, a simple solution seems to be the buy the e-book, ignore it and then download the same e-book from Z library.
I also feel the frustration though. I won't buy e-books unless it either has no DRM or if I know I can strip it easily afterwards.
