If you do away with money, what will you use as a medium of exchange of the value of production?
You run the scutwork of the economy with automation, robots, etc, which provides a basic living for nothing, and let people pursue their vocations.
The process for handling large allocations of resources is left as an exercise, but I'd favour direct democracy via recursive vote delegation ("liquid democracy"), at the most local possible scope (following the principle of subsidiarity).
Being free to do what you want is great, but most people don't know what they want, yet they have a natural disposition/desire/urge to lead or follow, and most definitely interact.
