Who knows, let's try it and see. I've heard all my life about how new ideas are potentially not economically viable, so we keep trying old ideas which proven not economically viable. My feeling is that the economy is such a large, chaotic, dynamic system that most people, including experts, have no idea what is theoretically viable or not viable. So making decisions based on "my first order analysis is that this is not economically viable" is misguided. You have to try it first and see how the system actually responds.
