Realistically, you're talking about a fantasy world.
Less harshly, if we want to have that kind of world, we're not going to get there by abandoning creatives by removing intellectual property protections as the first step. Within the current society, intellectual property law does more good than harm.
But besides that, I don't think a universal patreon-like support system is even ideal. I don't want to provide ongoing support for any creation/creator I appreciate. I like being able to just buy a book.
