So I'm working on a novel that uses the same main premise as Scott Meyer's Off to Be the Wizard (Magic 2.0 ) in which my protagonists discover that they live (as does everyone else) in a simulated universe. The first thing they do when they discover the source code to the universe is give themselves admin access to it, and then they started recruiting people with shared ideals, giving them mod access.
Now, their goal is to eliminate unconsensual death and suffering, and to increase joy and understanding for every sapient mind forever, so a significant chunk of the book will be spent on their creation of a post-scarcity economy/society.
Obviously, even in a simulated universe, you can never truly reach a post-scarcity situation because if there's a live show with 100 seats, and 101 people want to go, somebody's going to get left out. That being said, the bottommost levels of Maslow's Hierarchy of Needs can still be taken care of rather easily. (Being able to Copy+Paste reality helps with that.)
So, my question to you all: if you were a part of this organization, with either mod or admin access to the Source Code of Reality, how would you go about changing the world as it is now to become the post-scarcity world these protagonists imagine?
I'm trying to come up with economic structures, societal structures, and more that take advantage of the fact that ~95% of humanity is suddenly immortal, unaging, doesn't need to eat/sleep/breathe/etc. and that at least some people can fly or teleport. (Additionally, as a side note: people that accept the above also agree to sterility, unless they decide to leave Earth.)
