I think you missed a critical part of my comment - I see eliminating IP laws as critical to reducing the cost of living to zero. In this zero cost of living world, no one needs to pay rent.

In reality I believe zero is a worthy target but difficult to achieve, so I really expect us to hit "very low". In that world, the cost of living is so low that we can voluntarily support others at very little cost to ourselves, and with a minimum of Love for our fellow humans, those with income can support those without. In that world, authors are more free than ever to write what they truly believe. They have no publishers to please nor masses to target, and can write what they deem most valuable to write.
