I'd say what you're describing isn't undirected. You have goals and they sound positive, assuming that what you're inventing is positive (e.g., not torture devices). They use and refine your creativity, they potentially help others, they give you opportunities to partner with others to work toward a common positive goal, etc. I don't think that's idleness for the average person. It's more like nihilism and hedonism. I'm not arguing that jobs are the solution, to be clear -- just objecting to the terminology. If everyone would use free time in the way you would, there would be no problem.
