Let's say we live in a world where robots have taken 100% of the jobs. Our needs are met. We are free from working for a living.
Unfortunately, there is still only a few miles of prime beachfront property in Malibu, CA to build a house on and hundreds of millions will want to do so. Disneyland will only have a limited capacity at a given time, so hundreds of millions of people will not be able to spend every day there as they will want to do.
In other words, scarcity still exists. And if scarcity still exists, there will still be an economy and people will still be doing work. But what form does that take and how do you make these decisions?
My gut instinct is that, without actual jobs, then the people who get to live in the prime real estate areas are those with the best weapons / military as they can fight / scare off others. That might mean the biggest guns, the best ammo, the best robot workforce, or the best organized militarily or some other metric of military might. Humanity gets thrown back to a time before money was invented, and its about possessing a military powerful enough to take what you want. A world where robots do everything is a world where humanity becomes hyper militarized.
Instead of a money-based economy we have a military-based economy. Our social status and access to scarce goods and services depends on how strong our military and weapons are.
To put this in terms of WoW, the world becomes the devilsaur mafia. Theres only a limited amount of places to get devilsaur leather, and everyone is equal, so ungoro becomes hyper militarized and the biggest baddest military controls access.
