I have 4 library bookshelves (7 foot tall ones). And they're packed with books. *Bought* books.
But dealing with more current "online books" are a fraud. They 'sell' these books, but in actuality they're rentals due to DRM. I cant read them on Linux; I cant sell them; I cant read them on my phone; I can't print past their arbitrary print limits.
I have none of the same rights of these physical books.
So, yeah, I'll pirate.
