Right, but the Japanese government would take a big hit from that, and while that might not directly affect any future bidders, the effects of such a decision would haunt the bidding process for years to come I feel. If there’s no certainty that your city’s/country’s investment in the Games will yield results, why would you be lining up to host the Games at such a great cost?
I don’t think what your suggesting is a bad idea, but I think Japan counted too much on getting money from spectators and tourists. As whole, the international sports community has under valued the modern capabilities of television/streaming production, as well as, the doors those technological advancements open up.
