At the end of the day, somebody needs to do the work in order to create good. Adding layers of transactions can only reduce, not increase efficiency. If you, a person who knows something, want to achieve a public good in educating others on that thing, then the most efficient way of achieving that is just spreading the knowledge yourself. If you sold your knowledge in a book, and then used the money to pay someone else to write a book teaching the same thing, and then distributed that for free, you can only have lost efficiency. It's like asking "Why should I pay for college instead of working to make money to pay someone else to go to college and then teach that information to me": It's absurd, because it introduces entirely unnecessary transactions.
