That could be the case.
Or it might be the case that 10x as many people will purchase individual games than they would the pricey $250 it cost to get the ticket.
Businesses are constantly changing their distribution models and pricing e.g., Blockbuster used to exist, ridesharing didn't, phones once had cords on them, etc.
Probably the unfortunate part is the NFL has a monopoly on NFL football and the licensing deals exist. I would guess that if they let a bunch of players (e.g., Comcast, Netflix, Amazon, google, etc.) distribute football there would be a bunch of different ways to buy football.
IMO. Armchair speculation on my part.
