I'm being very radical here, but the thought of the only books being published being by people who actually want to be read rather than waant to be rich is not a problem for me. For craftsmen whose primary goal isn't to communicate or entertain, I'd suggest patrons. I'd certainly sponsor about 1/50 of a writer spread across a curated pool. I'd probably sponsor about 1/200 of a curator. They wouldn't have to even send me the books, I'd just buy them from the printer with the best quality to cost ratio.
