In a society as described (with essentially unlimited resources and energy) what will you do about the population explosion? Without warp drive to get to other star systems we'd end up like the Moties. Another Crazy Eddie utopia, not well thought out. Also, I doubt the vast majority of people would suddenly fulfill their potential and become rock star artists & scientists, achieving Great Things. Some would, but most will just partake of all that instantly available everything and disappear into the Holodeck, which presumably is also free. That future is more like Wall-E.
