But of course they can choose. They can choose to not go to those events and venues and do other things with their time.
And I expect that pro sports will look back on these moves and realize that they cannibalized their future fan growth for higher revenues today. I go to fewer pro sports games than I might otherwise both because of the absolute cost and because it feels bad to pay a bunch for a ticket and then also have to pay like $15 for a hot dog. And I take my kids to fewer than my parents took me to for similar reasons.
