Does it matter? The point isn't that tickets will become unaffordable, the point is that the sports leagues themselves will disappear.
Sports isn't something people need. Some sports leagues cost a lot of resources to run. If these sports leagues become less profitable, then some of the investment will move into other entertainment and your sports professional league will slowly disappear.
I don't think that the impact of less professional sports on a societal level will be very significant, but if the reason to get rid of ads at sporting events is to make them better, then it's (probably) counterproductive to take steps that kill off a large portion of those events.
Clearly this apocalyptic prediction begs the question of how much investment is required, since we're have a variety of shorts with different levels of spending, and raising over the past 20 years. If there were 2se less money in football, it's unlikely to disappear
I don't think this is apocalyptic. It's not that football would disappear, but professional football leagues would or they would be diminished. I don't know whether that has a significant negative impact on society.
