You need a limiting principle or there is no limit to the "better funding" you're asking for until you have a Library of Congress in every small town in America, to no positive effect.

What's the limiting principle you propose? It has to be something real libraries and library funding sources can take action on, because they have to take real-world actions on them. So this is not a time for aspirational speeches or vague exhortations to "do more", which is the exact opposite of a limiting principle anyhow. What is "enough"?

Sure, there are always solutions, and many of them usually involve more money. But that money usually doesn't just magically appear, even with plenty of Carnegie-types these days looking to whitewash their reputations through philanthropy. The money often is the problem that needs to be solved, and there's just no source for those funds.

Most books are not worth saving.

What's stopping you?

Someone can ask for a copy in the mail, cheaper than pre-emptively printing and storing thousands of copies of every version of every book.
