One problem is that work requires something to work on or with. For the most part, people don't really create out of nothing--they add to and build upon what already exists. They need land to farm, or materials to build with, or computers to work on. Even writers need languages to write in. As property becomes held more and more by fewer and fewer, and even intellectual property is becoming increasingly locked up there's less and less that is physically or intellectually available to build upon.
