It is not a big deal. Since the invention of the printing press any important
book has been duplicated by thousands, tens of thousands or even million of units.
Just taking one of those and "destroying them"(it is not destroyed, a digital copy with the ability of doing millions of copies is stored somewhere) is not problematic for Humanity.
By the way, I always search for second hand books. Most of the books there are garbage. Most people clean their shelves with the books they don't care about, but preserve the ones that are good. If they are young people that inherited a house and don't care about books, they pick and sell the good ones, giving away the bad books.
If you go to a recycling centre, the garbage to quality ratio is over 100 or more. That is, for every 100 books that are garbage there is one good quality book. It is very rare to find a jewel there.
