Oh ye of little faith.
Obviously that's a massive question, but if these really are a net producer on a big scale (MASSIVE if) then the upfront cost seems like something that can be worked out. We're talking trillions over time I'm sure, but in tiny chunks to start--a parking lot, a driveway, a small road, a small town, etc--that can be sorted out and seems like it's even something that can generate outside investors through advertising and whatnot.
