Re: Book projects generally work out
A book author that wants money to live on while writing, doesn't need all that money up front. So they don't need a Kickstarter. Patreon allows authors to write ebooks, post at least a chapter each month, and their readers each pay a small amount each chapter (with a per-month cap). If they don't post they don't get paid; if quality goes down too much then people will stop subscribing.
That way, the risk to the readers is much much lower - they're paying for results, not for the promise of results.
When the book is written, the author can give a complete electronic copy to their Patreon supporters, and/or publish the ebook, and/or do print-on-demand. If they want to, that's the time the author could do a Kickstarter for a bigger print run which is cheaper per book than print-on-demand.
