This is emotionally manipulative speech that provides no value to HN and only serves the purpose of bypassing peoples' logical reasoning circuits.

More manipulation - "think of the children!"
Copyright exists because people who produce content with low distribution costs (e.g. books) need some protection for their work being taken without compensation.
Fundamentally, you are never entitled to someone else's work.
There's already tens (hundreds?) of thousands of books in the public domain, and tens of thousands more under Creative Commons licenses (where the author explicitly released their work for free distribution). There's lectures on YouTube and MIT OpenCourseWare. There's full K-12 textbooks on OpenStax and Wikibooks. There's Wikipedia, Stack Exchange, the Internet Archive, and millions of small blogs and websites hosting content that is completely free.
There is no need for "a majority of the world had access to every book ever digitized" - and it's deeply morally wrong (theft-adjacent) to take someone else's work without compensating them on their terms.
