There is no artificial separation between work and play. Work is likely to be playful and enjoyable, and your leisure activities are likely to be productive. There is no lack of things to do in the world. There is always a need for improvement. Thus there is never such a thing as lack of work.
Unemployment is a result of self-serving manipulations of the money system.
Neither of these exist in HoloWorld. So, work here is not dependent on finding an activity that somebody will pay you for, no matter how useless or even harmful and irresponsible it is. However, there are essential factors involved in choosing one's line of work. To have a viable occupation requires that one scopes out the playing field well and chooses something that actually needs doing and would be valuable to somebody. You would not do that in isolation, it would depend on the environment you are in and the people you are with.
