issue is - what's the product of sport? does the good example of being in shape translates directly to cash necessary to run the sport? sports betting is the one and only natural fit as the source of income
What do you _mean_? Advertisers pay tons of money because tons of people watch sports. Countries provide resources to teams because they are a source of national pride. Not to mention half of teams are bankrolled by insanely rich people in order to build their reputation and prestige.
So how can betting be the only natural fit as a source of income? The argument does not make sense.
entertainment and sponsorship is bit different than sports gambling - less related to actual match results. what I mean is - sports don't make a product. there's no food you can eat, car you can drive etc.
