Any reason to keep pirating books in 2026?

I'd gotten a bunch of stuff from OceanOfPDF and Internet Archive before learning about Libby or e-lending as a whole. Haven't determined how reliable these are for getting all the books I want. Maybe I'm just too old fashioned to legally borrow e-books.

About the biggest advantages may be for books being removed from libraries, as well as scanlations and out of print books. Know any other advantages?

I've noticed general-discussion book subreddits to be exceptionally hostile to ebook piracy, likely because they know legal free alternatives better than I do. I'm such a boomer.
