Except for one minor problem. Energy is not free and unlimited for us with our current technologies. If we had limitless power, sure, absolutely. Time of scarcity is over.
Until then, you are simply wrong.
Energy is free. There are plenty of technologies that can produce practically limitless energy for very little cost (eg. Cold Fusion, Vacume Energy). The only thing is that governments and big corporations have been actively suppressing this technology for their own gain.
